Private 2FA authenticators
13 apps, each with a privacy passport
An authenticator app makes the six-digit codes that protect your logins. What matters is that the secrets stay on your device or sync end-to-end encrypted, and that you can export them, so losing a phone never locks you out. Some sync across devices with an account; others are offline only and rely on encrypted backup files.
