Chrome has several different sign-in switches, and changing the wrong one can leave automatic sign-in enabled. For saved website passwords, open More (⋮) > Passwords and autofill > Google Password Manager > Settings and turn off Sign in automatically. Chrome will then ask before using saved credentials. Separate controls govern Chrome itself signing in during Gmail access, Android’s Password Manager, and third-party “Sign in with Google” prompts.
First identify which sign-in behavior you want to stop
“Auto sign-in” can describe four different actions. The correct fix depends on whether Chrome is filling a saved website password, signing the browser profile into Google, displaying an identity-provider prompt, or enforcing a company policy.

| Behavior | Setting to change | Platform | Result | Who controls it |
|---|---|---|---|---|
| A website opens with a saved username and password without asking | Sign in automatically in Google Password Manager | Desktop Chrome | Chrome asks for confirmation before using saved sign-in information | You |
| Chrome signs its profile in when you sign in to Gmail or another Google service | Chrome profile’s Google services sign-in preference | Desktop Chrome and other supported Chrome platforms | Choose Sign in, Don’t sign in, or Ask every time | You, unless an administrator manages the browser |
| An identity provider displays a “Sign in with Google” or similar prompt | Block sign-in prompts from identity services | Chrome site settings | Blocks the prompt while leaving ordinary sign-in buttons and username/password forms available | You |
| Android automatically submits saved credentials | Auto sign-in in the device Password Manager | Android | Stops automatic use of saved credentials on the device | You or the device administrator |
| A work or school browser forces a sign-in state | Chrome Enterprise browser sign-in policy | Windows, Mac, Linux, Android, and iOS managed environments | The administrator can disable, enable, or require browser sign-in | Chrome Enterprise administrator |
Turning off one control does not change the others. For example, disabling website password auto sign-in does not automatically stop Chrome from signing its profile into Google when you open Gmail.
Disable automatic sign-in to websites on desktop Chrome
This is the setting to use when Chrome silently uses a username and password saved in Google Password Manager. Google describes the effect this way: “If you want to confirm your saved info when you sign in, you can turn off ‘Sign in automatically.’”

- Open Chrome on your computer.
- Select the three-dot More menu in the upper-right corner.
- Choose Passwords and autofill, then select Google Password Manager.
- In Google Password Manager, select Settings in the left-hand navigation.
- Turn Sign in automatically off.
With the switch off, Chrome should request confirmation before it uses saved sign-in information on a site or app. The saved entries remain in Password Manager; this switch changes whether Chrome submits them automatically. If you also want a password removed, delete that individual saved entry in Google Password Manager rather than relying on the switch.
What this setting does not change
- It does not sign you out of websites where a session is already active.
- It does not remove saved usernames or passwords.
- It does not control whether the Chrome browser profile signs in to Google.
- It does not suppress identity-provider prompts such as “Sign in with Google.”
If a particular site still opens an existing account without showing a password prompt, sign out of that site first. The Password Manager switch controls Chrome’s use of saved credentials; it is not a site-session or cookie deletion control.
Stop Chrome itself signing in when you open Gmail
Chrome can ask whether to sign the browser profile into Chrome when you sign in to a Google service. This is separate from filling a saved password on a non-Google site. Google’s help wording is: “When you sign in to your Google Account through a Google service like Gmail, you may be asked if you also want to sign in to Chrome.”

Open Chrome’s settings for the current profile and find the Google services sign-in preference. In current desktop releases this is reached through the profile area in Chrome Settings, often under You and Google or Sync and Google services; wording can vary by Chrome version.
Choose the behavior you want
- Sign in: Chrome signs the browser profile in when you sign in to your Google Account through a Google service.
- Don’t sign in: You can use Gmail or another Google service while the Chrome profile remains signed out.
- Ask every time: Chrome displays a choice each time a Google-service sign-in could also sign the browser in.
Choose Don’t sign in when you never want a Google-service login to enroll the browser profile. Choose Ask every time when you occasionally use Chrome sync or other profile features but want an explicit decision at each login.
If Chrome is already signed in
Changing the preference affects future Google-service sign-ins. If the profile is already signed in, use Chrome’s profile controls to sign out of Chrome separately; signing out of a website alone does not necessarily sign the browser profile out.

Turn off auto sign-in on Android
Android exposes this control through the device’s Password Manager rather than the desktop Chrome menu. The exact appearance of Settings can differ by phone manufacturer and Android release, so use the Settings search field if the menu is organized differently.

- Open the Android device’s Settings app.
- Search for Password Manager.
- Open the Password Manager settings result.
- Find Auto sign-in and turn it off.
This prevents the Password Manager from automatically submitting saved credentials. It does not delete saved passwords, and it is not the control for Chrome-profile sign-in during Gmail access. If your phone is managed by an employer or school, an administrator may restrict or override available settings.
Block “Sign in with Google” and other identity-provider prompts
A website can show a browser-mediated identity prompt even when you are not asking Chrome to fill a saved password. To suppress those prompts while retaining normal login methods:

- Open Chrome’s Settings.
- Go to Privacy and security.
- Select Site settings.
- Open Additional content settings.
- Select Third-party sign-in.
- Choose Block sign-in prompts from identity services.
Chrome explains that this blocks the prompt supplied by an identity service. Ordinary sign-in buttons, including a site’s own “Sign in with Google” button, and conventional username-and-password forms remain available. Therefore, this setting reduces unsolicited prompts; it does not make Google-account login impossible.
When to use this setting instead of Password Manager
- Use Password Manager’s switch when Chrome is submitting a stored username and password.
- Use the third-party sign-in setting when a browser prompt appears before you choose a site login button.
- Use the Chrome profile preference when Gmail sign-in is also asking to sign Chrome in.
Understand administrator-controlled Chrome sign-in
On a managed work or school device, your local switch may not be decisive. Chrome Enterprise administrators can apply a browser sign-in policy on Windows, Mac, Linux, Android, and iOS. The policy has three administrator choices:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Disable browser sign-in: users cannot sign the Chrome browser profile in.
- Enable browser sign-in: browser sign-in is available to users.
- Force users to sign-in to use the browser: a browser sign-in is required before Chrome can be used.
If a setting is locked, missing, or immediately reverts, look for a “Managed by your organization” message in Chrome’s menu or settings page. Contact the organization’s administrator; repeatedly changing Password Manager or Google-service preferences will not override an enforced browser policy.

Troubleshoot the common “it still signs me in” cases
Chrome fills a website without asking
- Return to More > Passwords and autofill > Google Password Manager > Settings and verify Sign in automatically is off.
- Check whether the behavior is an existing website session. Sign out of the site, then test again in a new tab.
- If the account should never be used on that device, remove its saved credential from Google Password Manager instead of only disabling automatic submission.
Gmail signs Chrome in even though website auto sign-in is off
Change the Chrome profile’s Google services preference to Don’t sign in or Ask every time. The Password Manager switch only governs saved credentials; it does not govern browser-profile enrollment.
A “Sign in with Google” prompt keeps appearing
Use Settings > Privacy and security > Site settings > Additional content settings > Third-party sign-in, then select Block sign-in prompts from identity services. A site can still offer a normal login button after prompts are blocked.
The option is unavailable or cannot be changed
Check whether Chrome is managed. Enterprise policy can disable browser sign-in, enable it, or require it. On Android, device management can also limit Password Manager behavior. Only the administrator can change an enforced policy.
You want to reverse the change
Return to the same control and restore it: enable Sign in automatically for saved website credentials, select Sign in or Ask every time for Chrome profile behavior, or choose the identity-service prompt option that allows prompts again. On Android, re-enable Auto sign-in in the device Password Manager settings.
Which setting should you choose?
- Maximum confirmation for saved passwords: turn off desktop Sign in automatically and Android Auto sign-in.
- Use Gmail without enrolling Chrome: set the Chrome profile preference to Don’t sign in.
- Decide at each Gmail login: choose Ask every time.
- Stop unsolicited identity prompts: block prompts under Third-party sign-in.
- Work or school browser: ask the administrator which Chrome Enterprise policy is applied.
These controls are intentionally separate: saved website credentials, the Chrome profile, identity-provider prompts, Android Password Manager, and enterprise policy each operate at a different layer. Selecting the layer that matches the symptom is what prevents Chrome from signing in automatically without disabling unrelated Google features.
