1Password

1Password keeps your logins, credit cards, and secure notes in one encrypted vault accessible from any device. It generates strong passwords, autofills them in browsers and apps, and alerts you to compromised credentials.

What it does

Your data is encrypted with a master password and a secret key — even 1Password can't read it. The app syncs via your own account (not third-party cloud), and the Watchtower feature scans for weak, reused, or breached passwords.
