1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsIf a breach exposed your username and password, change that password promptly on the affected service, then change it anywhere else you reused it. Use the service’s official app or website—not a link in an unexpected message—and secure recovery options, active sessions, and email settings before watching for follow-on scams.
1. Change the exposed password—and every reused copy
Go directly to the affected service’s official website or open its official app. If you can still sign in, replace the exposed password with a strong, unique one. Do not use that replacement on another account.

Then change the password on every other account where you used the exposed password. Stolen credentials can be tried against the breached account and against other services where the same login may work. The Federal Trade Commission (FTC) explains that scammers buy credentials stolen in breaches and use them to log in to the affected account in its guidance on two-factor authentication.

2. Close existing sessions and check account access
A password change may not end sessions that were already open on other devices. Look in the account’s security settings for an option such as “Sign out of all devices,” “Log out of other sessions,” or “Manage devices,” and use it. The precise label and location vary by service.
The FTC recommends signing out on all devices after suspicious account access: “That way anyone who’s logged in to your account on another device will get kicked out.” See its consumer alert about hacked email or social media accounts.

- Requires 3 "AAA" batteries (included)
- Unit auto-locks for 30 minutes after 5 consecutive incorrect PINs
While reviewing security settings, check recent activity, recognized devices, linked apps, recovery email addresses, and phone numbers. Remove unfamiliar devices or connections and correct recovery details you do not recognize. For email accounts, also inspect forwarding rules and filters: an unauthorized rule can copy messages or hide security alerts, potentially helping an intruder maintain access or interfere with future password resets. The UK National Cyber Security Centre’s account-recovery guidance and FTC hacked-account advice both address reviewing these settings.

3. Turn on two-factor authentication
Enable two-factor authentication (2FA), also called multifactor authentication (MFA), if the service offers it. It requires an additional factor beyond the password, so a stolen password alone does not satisfy the sign-in requirement. The Cybersecurity and Infrastructure Security Agency explains how MFA adds another layer of protection.
Use a method the affected service supports and that you can recover if you lose access to it. Depending on the service, options may include an authenticator app, a one-time code, or a physical security key. A security key must be compatible with the service; check the service’s official instructions before relying on one. No single method is available everywhere, and the best fit depends on the service’s options and your recovery needs. Keep any backup or recovery codes somewhere secure and separate from the account.
4. If you are locked out, recover access safely
Use the provider’s account-recovery process from its official website or app. Type the known address yourself or use a trusted bookmark. Do not follow an unexpected password-reset or recovery link in an email or text; a breach can prompt convincing impersonation attempts.

If you regain access, change the password to a unique one, end other sessions, review recovery information and recent activity, inspect email forwarding and filters where relevant, and enable 2FA. If the provider’s recovery process fails, contact its official support channel rather than a phone number or link supplied by an unsolicited message.

5. Watch for targeted messages and assess what else was exposed
Be alert for emails, texts, or calls that refer to the breach, claim to help secure your account, or pressure you to share a password or verification code. Navigate to the service independently to check alerts. Do not disclose one-time codes to someone who contacts you unexpectedly.
If the breach notice says information beyond login credentials was exposed, follow guidance suited to that data. In the United States, the FTC’s IdentityTheft.gov data-breach resource provides tailored next steps. Exposure of a Social Security number (SSN) warrants particular attention, including checking for accounts you do not recognize. Outside the U.S., use your country’s identity-theft or privacy regulator resources; IdentityTheft.gov is a U.S.-specific service.
