Description

2FAS is a free, open-source two-factor authentication app for Android and iOS that focuses on ease of use without requiring an account. Tokens are stored locally and can be backed up to your own cloud storage in encrypted form. A companion browser extension lets you approve logins on your desktop with a single tap on your phone, while keeping the secrets on your device. 2FAS supports importing from other authenticators and is a straightforward, privacy-friendly alternative to Google Authenticator and Authy.
