About this extension
authi.me is a two factor authenticator app that generates secure time-based one-time passwords and syncs them across your devices through the cloud.
There are no accounts required. Use authi.me to get your 2FA codes for a secure login on any supported website, platform, or application like Google, Microsoft, and social media accounts.

When you need a secure login, a password alone is not enough. Adding two factor authenticator protects your accounts from unauthorized access.
A TOTP generator provides time-based 2FA codes that change every 30 seconds.
Because these 2FA codes change constantly, your secure login process is protected against password theft.
authi.me is built to be a fast and reliable TOTP generator for everyday use.

How to use authi.me for two factor authentication:
When a website asks you to set up two factor authentication, scan the provided QR code with authi.me.
authi.me will act as your TOTP authenticator and immediately start displaying 2FA codes.
During your next secure login, open authi.me, read the current 2FA codes, and type them into the website.

Features of authi.me:
- Cloud sync for your 2FA codes: If you lose your phone, your two factor authentication access is not lost. The 2FA codes sync automatically across your devices.
- Works as a standard TOTP authenticator: authi.me supports the standard time-based two factor authentication protocol used by major websites and applications like Google, Microsoft, and social media accounts.
- Fast secure login: The app opens quickly so you can read your 2fa codes and finish your secure login without waiting.
- No account needed: You do not need to create a profile or provide personal data to use this TOTP generator.

Many online services now require a secure login. Whether it is your email, bank, or social media, two factor authentication is the standard method for protection.
By keeping all your 2FA codes in one TOTP generator available on all your devices, you save time.

Protect your accounts today. Download authi.me, set up your TOTP authenticator, and start using 2FA codes to guarantee a secure login for all your online profiles.
