Time-Based Codes for Everyday Sign-Ins
Proton Authenticator keeps time-based one-time passwords in a focused vault for daily sign-ins. Each saved account can present its issuer, account label, current six-digit code, and countdown so you know when the value will rotate. The home view puts Create new code near the center of the workflow, keeping the first action clear instead of hiding it in a large menu.
When a service asks for a second factor, copy the current value into its sign-in form and return when another code is needed. Codes are generated on the device and can work without an internet connection, which suits travel, desktop sign-ins, and accounts that need a second step after the password.
Create Codes with QR Scanning or Manual Keys
Adding a new account follows the normal QR-code or secret-key workflow. Choose Create new code, scan a QR code with the phone camera, or select manual entry when a service supplies a key. Adding a title and issuer makes the entry easier to recognize later, especially when several accounts use similar names.
The Android setup path keeps these choices close to the first task, while the home view also offers Import codes for people who already have a collection elsewhere. This lets Proton Authenticator handle a fresh 2FA setup or a gradual move from another tool without forcing users to rebuild every account from memory.
Move Existing Accounts Between Authenticators
Import codes is designed for users who are switching authenticator apps or consolidating several devices. The provider chooser includes 2FAS, Aegis Authenticator, Authy, Bitwarden Authenticator, Ente Auth, Google Authenticator, and LastPass Authenticator, giving each migration a recognizable starting point. Choose the provider that currently holds the accounts, follow its export instructions, and bring the resulting file or QR-based backup into Proton Authenticator.
The same workflow is useful when replacing a phone, leaving a service, or keeping a separate authenticator for privacy. Proton Authenticator also supports exporting codes, so moving away later remains practical. Review account labels after importing and keep an additional secure backup before removing the previous app.
Sync, Back Up, and Protect Your Code Vault
People who use Proton Authenticator on more than one device can connect a Proton Account to sync codes across Android and desktop platforms. The standalone vault remains usable without an account, while sign-in adds a way to keep the same entries available when moving between supported devices. Encrypted backups and direct export provide additional ways to recover or move a collection when a phone is replaced.
Local protection fits into the same workflow. Proton Authenticator supports biometric or PIN-style access options where available, and its settings entry keeps security controls close to the vault. This combination suits users who want a focused code app first, with cross-device continuity available when their routine calls for it.
