2FAS is an easy-to-use authentication app that protects access to your online services and accounts.

Relying on a single password for your personal accounts, like Facebook or Instagram, often puts your data and sensitive information at risk.

The 2FAS Authenticator App generates one-time codes called Time-based One-time Passwords (TOTP) or HMAC-based (event-based) One-time Passwords (HOTP) for your account. By creating these codes offline and changing them every 30 seconds or every login, 2FAS drastically increases the security of your information.

Christian Nicolau (ID: 00000007329b50ee) Voted 1 ★ - Updated 10/23/2023 I am trying to log in to GitHub. I am using the brave browser. My android phone is paired to this extension via the 2fas Auth app. Upon receiving the browser request on the phone, I am told to 'add services to the 2FAS app'. What services are or how to add them to the app is nowhere to be found. Conclusion: The whole process is not working. Case closed.
