2FA, passwords and backups in one app

2FA Authenticator SL is designed to keep sensitive information close to you and give you clear control over how it is displayed, imported and backed up.

Scan a service QR code or enter the secret key manually. Organize accounts into categories and keep 2FA codes hidden until you choose to reveal them.

  • QR scanning and manual entry
  • Categories for better organization
  • Hidden codes with temporary reveal
