If you know your current AT&T sign-in password, change it from your account profile: sign in, open Your info, find Password, choose Edit, and save a new password. If you cannot sign in because you forgot it, use AT&T’s reset page with your AT&T ID, last name, and an available verification method. Afterward, update saved passwords, review recovery details and account users, and check the separate passcodes that protect account changes.
The menu labels below reflect AT&T’s support instructions updated April 3, 2026. AT&T can change its interface, so use the linked official pages if a label or screen differs.

Choose the right AT&T password path
Your sign-in password and your account passcode are different credentials. Use the path that matches your situation rather than trying to change a passcode when you actually need to reset a password.

How to change your AT&T password when you know it
-
Open your AT&T account profile and sign in if AT&T asks you to authenticate.
-
Under Your info, locate Password.
-
Select Edit.
-
Enter the new password, confirm it if the page requests confirmation, and save.
-
Sign in again where necessary with the new credential. Update password managers, browsers, phones, tablets, streaming boxes, mail clients, and other apps that stored the old password.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
If you use the same AT&T ID and password for AT&T Mail, enter the new password in your mail app or browser sign-in as well. A device that continues submitting the old password can repeatedly fail authentication or trigger additional security checks.
What to check before saving
Make sure you are changing the intended AT&T ID if you manage more than one account. Check the spelling of the new password and avoid copying an extra space at the beginning or end. A password manager can create and save a random credential, but it must fit AT&T’s 8–24 character limit and accepted-character list. Keep the new entry labeled clearly so another AT&T ID is not overwritten.
For the current menu path and any changed labels, refer to AT&T’s support page (updated April 3, 2026): https://www.att.com/support/article/my-account/KM1008941/.
How to reset an AT&T password you forgot
A reset is different from an ordinary change because AT&T must verify that you control the account before accepting a new credential.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
-
Open AT&T’s password-reset page directly. Typing the address or navigating from AT&T’s own site is safer than selecting a reset link in an unexpected email or text.
-
Enter your AT&T ID and the last name associated with that ID.
-
Choose one of the verification methods AT&T offers for the account and complete the prompts. The available choices depend on the recovery information already on file.
-
Enter and confirm a new sign-in password when AT&T presents the reset form.

If no recovery method is available or the reset still does not let you sign in, AT&T’s instructions list 800.288.2020 as the support fallback. Use the number shown in AT&T’s official guidance rather than a number supplied by an unsolicited caller or message. See AT&T’s Change or Reset Your Sign-in Password page for the latest recovery options.
Why the reset may offer different choices
AT&T shows verification methods based on the recovery information attached to the AT&T ID. One customer may see a phone option while another sees an email or another available method. Do not assume that an option missing from your screen is a temporary error. First confirm that you entered the correct AT&T ID and associated last name. If the account has no usable recovery method, the official support number is the next step.
AT&T password rules and how to choose a safer one
AT&T lists these sign-in password parameters:
- Length: 8–24 characters.
- Accepted character types: uppercase letters, lowercase letters, numbers, and the special characters
+ = # ? * $ ! _ -.
Those are the character types AT&T says it accepts; the support guidance does not say that every password must contain a particular combination of character classes. A long, unique password is the important security objective.

- Do not use your name, address, birthday, phone number, account number, common words, or details visible on social media.
- Avoid obvious sequences such as
123456orabcdef. - Do not reuse the AT&T password for another service or another AT&T ID. A breach at a different service can expose a reused combination.
- Use a password manager to generate and store a random password within the 8–24 character limit, or create a long, uncommon passphrase that no other account uses.
AT&T’s account-protection guidance recommends unique credentials and different passwords for multiple IDs. It does not establish a universal rule that changing your password signs out every existing session, so contact AT&T if you need confirmation about active sessions after a change.
Update every place that saved the old password
Changing the credential on the website does not automatically replace copies saved elsewhere. Work through this checklist immediately after a change or reset:
- Browser password storage and password-manager entries.
- AT&T Mail in a web browser, phone, tablet, desktop mail program, or smart device.
- AT&T account pages bookmarked inside carrier or billing apps.
- Any device that uses the AT&T ID for account management or authentication.
When an app rejects the new password, delete its stored AT&T credential and sign in again instead of repeatedly submitting the old one. Check older phones, tablets, and computers too; an overlooked device can continue sending the old credential. If you changed the password because of suspected compromise, complete the security review below before assuming the account is clean.
Secure your account after changing the password
A new sign-in password protects one authentication route. AT&T recommends checking the recovery channels, account access, and separate passcodes that could still allow changes.
Review recovery information
- Confirm that the phone numbers available for password recovery are yours and still reachable.
- Check the recovery email address. Replace it if it is no longer private or controlled by you.
- Remove outdated contact details that could send verification codes to someone else.
These checks are part of AT&T’s account-protection recommendations in Protect Your AT&T Account (updated April 12, 2026). Treat recovery information as carefully as the password itself: anyone who controls a recovery channel may be able to start another reset.
Know which credential does what
AT&T uses separate credentials for separate actions:
| Credential | Primary use | What it is not |
|---|---|---|
| Sign-in password | Logging in to your AT&T account online | Not the same as an account or wireless security passcode |
| Account passcode | Verifying account activity in an AT&T store or on a call | Not your website sign-in password |
| Wireless extra-security passcode | Additional online protection for eligible wireless accounts | Not available for every account or business account |
AT&T describes these distinctions in Learn About AT&T Account or Extra Security Passcodes (updated April 12, 2026). Changing one credential does not mean the others changed too.
Change the account or extra-security passcode when necessary
-
Open your AT&T account profile.
-
Choose Settings.
-
Scroll to Passcode and choose Edit.
-
Follow the verification prompts and save the new passcode.

AT&T lists new passcodes as 4–8 digits. Avoid three or more sequential numbers or three or more identical numbers. Extra-security management is available for wireless accounts that are not combined with AT&T Internet or U-verse TV; AT&T says business accounts do not have this option. The eligibility and combination limits come from AT&T’s passcode guidance, so an unavailable option may be expected rather than a sign that the page is broken.

Check secondary and authorized users
Review who can access or authorize activity on the account. Remove secondary online users who no longer need online access and wireless retail authorized users who should not be able to make account changes. AT&T treats these as different types of access; check both lists where they apply. This is especially important after a household change, employee departure, or any situation in which another person previously helped manage billing or service.
Consider Wireless Account Lock
For wireless customers, AT&T offers Wireless Account Lock. AT&T says the setting disables some transactions and account changes for all devices and lines on the wireless account. It is a useful additional barrier, but it should not be described as blocking every possible change. Review the control in your account and AT&T’s current terms before relying on it as your only protection.
What to do if you suspect someone accessed the account
Act through AT&T’s site or app that you open yourself, not through an unexpected message. If you shared a password, received an unfamiliar verification request, or see an account change you did not authorize:
-
Change the sign-in password immediately and do not reuse the old one.
-
Change the account passcode and, where eligible, the wireless extra-security passcode.
-
Review recovery phone numbers and email addresses; replace anything you do not control.
-
Check secondary online users and authorized wireless users, removing access that is no longer legitimate.

If your AT&T Mail account may be hacked
Email access can let an intruder reset other accounts, so check more than the password. AT&T’s hacked-email guidance recommends this sequence:
-
Change the AT&T Mail password.
-
Check the phones and computers that access the mailbox for malware or other signs of compromise.
-
Inspect mail settings for unexpected forwarding rules or POP accounts.
-
Review the signature, vacation response, blocked addresses, and contacts for changes you did not make.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Change versus reset: which route should you use?
Use the signed-in change flow when you know the existing password and can reach the profile. It is the shortest route and lets you review account settings immediately afterward. Use the reset flow when the password is forgotten or rejected and you cannot authenticate normally. Resetting requires the AT&T ID, associated last name, and a verification method that AT&T recognizes.
If you can sign in on one device but not another, change the password from the working session first, then remove the old credential from the failing device. If you cannot sign in anywhere, do not keep guessing passwords; start the official reset process. Repeated guesses can create more failed sign-ins without solving the recovery problem.
Troubleshooting common problems
The “Edit” option is missing
Confirm that you are in the account profile’s Your info section, not a billing or device page. Sign out, reopen AT&T directly, and try again. If AT&T has changed the layout, use the linked support article for the current path.

A phone or mail app keeps rejecting the new password
Remove the old saved credential from the app or operating system, then add the account again with the new password. Check every device using the same AT&T ID; one forgotten device can continue sending the old credential.
You changed the password but still see suspicious activity
Change the account and eligible wireless passcodes, inspect recovery details and users, and review AT&T Mail forwarding and other settings. Do not assume that changing the sign-in password alone removed every active session; AT&T’s cited guidance does not make that universal claim. Contact AT&T if you need confirmation about session status or account activity.

- Recovery phone numbers and email are current and private.
- Account and wireless security passcodes were reviewed or changed when appropriate.
- Secondary online users and authorized users are still legitimate.
- Wireless Account Lock was considered if you use eligible wireless service.
- Unexpected email settings, forwarding, and devices were checked if compromise involved AT&T Mail.
- All resets were started from AT&T directly, never from an unsolicited link or caller.
Frequently Asked Questions
How do I change my AT&T password online?
Sign in to your AT&T account profile, open Your info, find Password, choose Edit, enter the new password, and save it. Then update password managers, browsers, devices, and AT&T Mail that used the old password.
How do I reset my AT&T password if I forgot it?
Open AT&T’s password-reset page directly. Enter your AT&T ID and the associated last name, choose an available verification method, and follow the prompts to create a new password. If recovery does not work or no method is available, AT&T lists 800.288.2020 for support.
What are AT&T’s password requirements?
AT&T lists passwords of 8–24 characters and accepts uppercase and lowercase letters, numbers, plus these special characters: + = # ? * $ ! _ -. AT&T advises a long, unique password and does not state that every password must contain a prescribed mix of character types.
Is my AT&T account passcode the same as my sign-in password?
No. The sign-in password is for online access. The account passcode is used to verify activity in an AT&T store or on a call. Eligible wireless customers may also have a separate extra-security passcode for online wireless sign-in.
How do I change my AT&T account passcode?
Open your account profile, choose Settings, scroll to Passcode, select Edit, and follow the prompts. AT&T lists new passcodes as 4–8 digits and advises avoiding three or more sequential or identical numbers.
Does changing my AT&T password sign out every device?
AT&T’s cited guidance does not make a universal claim that a password change signs out every active session. Update saved credentials on each device and contact AT&T if you need confirmation about current sessions.
What should I do after an AT&T compromised-password alert?
Open AT&T directly rather than using an unexpected alert link, change the AT&T password, change any reused password on other services, and review recovery information and account users. The alert can indicate that the combination appeared in a breach outside AT&T; it does not by itself prove an AT&T breach.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →What should I check if my AT&T Mail account was hacked?
Change the mail password, check devices for malware, inspect forwarding and POP settings, and review the signature, vacation response, blocked addresses, and contacts for unauthorized changes. After checking devices and settings, change the password again.
The Bottom Line
For a known password, use Your info > Password > Edit. If you forgot it, reset through AT&T with your ID, associated last name, and identity verification. A secure recovery does not end with the password: update saved credentials, verify recovery contacts, review users, change separate passcodes when needed, and investigate mail settings or reused passwords if compromise is possible.
