Pinterest keeps signing you out can happen for several common reasons. Here are practical steps to diagnose and fix the issue: What to check first

• Multiple accounts or automatic login: If you’re signed into more than one Pinterest account in the same browser or device, Pinterest may switch you or log you out. Ensure you’re using a single account per device and consider signing out of other accounts to test. Additionally, if you use a password manager or browser autofill, verify it isn’t triggering frequent sign-ins/sign-outs.
• Password or security triggers: If Pinterest detects unusual activity or a password change is required, it may log you out as a security precaution. Consider changing your Pinterest password from the mobile app or a trusted device and re-signing in. This can reset any stale session tokens that cause repeated logouts.
• Connected account sign-in methods: If you sign in with Facebook, Google, or Apple, make sure those linked accounts are still active and haven’t been removed or reauthenticated recently. Re-link if needed.

Device and app considerations

• Browser vs app: Test staying logged in on both the mobile app and a desktop browser. If it only happens on one, the issue is likely related to that environment (cookies, extensions, or browser settings).
• Clear cookies and cache (browser): Clearing cookies and cache can resolve corrupted session data. After clearing, sign back in to Pinterest. Note that you’ll need to re-enter credentials on all sites you sign into.
• Extensions and privacy settings: Ad blockers, privacy extensions, or strict tracking prevention can interfere with login sessions. Temporarily disable extensions to see if the issue persists.
• Private/incognito mode: If you’re using private browsing, sessions won’t persist between tabs or browser restarts. Use a normal window to test.

network and account protections

• IP or location triggers: Some networks (especially shared or public networks) can trigger security checks that sign you out. Try a different network (home Wi‑Fi, mobile hotspot) to see if the behavior changes.
• Security alerts and email: If Pinterest detects suspicious activity, you may receive a security alert or force logout across devices. Check your email for any notices and follow the security steps provided.

When to seek official help

• If none of the above resolves it and you consistently get logged out on multiple devices, it’s worth contacting Pinterest support. Provide details like:
  • Which device(s) and browser/app version you’re using
  • Whether you sign in with password only or via Facebook/Google/Apple
  • Any recent changes (password updates, app updates, network changes)

If you’d like, tell me:

• Are you seeing this on mobile, desktop, or both?
• Do you sign in with a password only or via another service (Facebook/Google/Apple)?
• Have you recently changed your password or updated apps or browsers?

I can tailor steps for your exact setup.
