Related questions

Is 2FAApp an authenticator app? No. 2FAApp helps you choose, set up, test, troubleshoot, and recover 2FA. It does not provide a mobile app that stores your live account secrets. Can an online 2FA generator replace my authenticator app? No for normal account protection. A browser generator can help with test secrets or debugging, but real account secrets should live in a trusted authenticator or hardware-backed setup. Should I use SMS or an authenticator app? Use an authenticator app when the platform supports it, especially for high-value accounts. SMS can be better than no 2FA, but it is more exposed to number takeover and delivery issues.
