How to logout yahoo mail from all devices?

Answer 1 — practical steps: - From a browser: Go to Yahoo Mail, click your profile picture → Account Info → Recent activity (or Manage devices) and you’ll see devices/sessions. Click Sign out next to the sessions you want to remove or choose Sign out from all devices if available. - If you suspect a breach: Change your password immediately and enable two-step verification — that usually forces other sessions to sign out. :contentReference[oaicite:6]{index=6}

Answer 2 — short tip: If you can’t access the account, reset the password (use the recovery options). Once the password is changed, most other sessions will be forced to re-login — which effectively signs them out. Also check connected apps in Account Security and remove any you don’t recognize. :contentReference[oaicite:7]{index=7}
