Authenticator - 2FA & Password

Description

Authenticator is a full-featured 2FA authenticator app focused on privacy and usability. It generates one-time passcodes (OTP) to help you enable two-factor authentication (2FA) for your important accounts.
Whether you log in every day, manage lots of accounts, use multiple devices (phone/tablet/watch), or need backup and migration, Authenticator provides a stable, smooth, and reliable experience.

What you can do with Authenticator

- Enable 2FA for email, social, cloud services, games, work accounts, and more
- Generate codes anytime offline—no internet required
- Stay in sync across devices: quickly view codes on your phone, tablet, or watch
- Use cloud sync plus import/export for a safer, easier device switch or reinstall
