Run a security check
Find weak, reused and breached passwords and fix the most important first.
Steps
Open Security. Checks run on your device; your passwords are never sent anywhere.
Start with anything marked breached or reused.
Use Fix your passwords, one at a time: choose Open change-password page, sign in to the site, then choose Generate new password.
Copy the new password into the site, save it there, then choose Save in Passkey-X. The item leaves the list automatically.
