Top 15 Authenticator Alternative and Similar Softwares | Dec 2024

Authenticator is a simple, free, and open source two-factor authentication app. It helps keep your online accounts secure by generating unique one-time passwords, which you use in combination with your other passwords to log into supporting websites.

- Secure: All data is stored in encrypted form on the iOS keychain
- Compatible: Full support for time-based and counter-based one-time passwords as standardized in RFC 4226 and 6238
