Multi Factor Authentication

Multi-Factor Authentication mainly exists because password-based authentication is so unsecure. Therefore, the whole industry has created an industry of patches, and gave them nice acronyms such as MFA (Multi Factor Authentication) and 2FA (Second Factor Authentication). Ultimately, MFA is here to protect you from an unknown person trying to access your online data, such as your personal details or your financial assets.

Ever wondered what a Second Factor Authentication is?

This short animated video will give you a good understanding of Second Factor Authentication (or 2FA).

Why Authenly?


Authenly provides one of the most secure Second Factor Authentication solutions out there.

The 2FA secret key stays on your device, and does not move from there. The Authenly cloud does not store any password, any 2FA secret, or any 2FA backup code either. Finally, we encrypt every important piece of information with the best and most recent crypto algos.


It takes a few minutes to register with Authenly.

All we ask is a proof of ownership of an online identity (generally an email address). Of course, if this email is not yours and belongs to another Authenly user, they will get notified right away! That's how it should be.


Authenly keeps you secure and going!

Most TOTP solutions will let you down at the first attempt to recover your account. Authenly is different. You are in full control of your backup/restore policies, so that you never risk getting locked out of your accounts, thanks to Authenly's unique offline un-hackable backups.

Need to understand and setup TOTP?

This short animated video will give you a good understanding of what is a Timed One-Time Password (or TOTP).

Are all MFA/2FA are made equal?

You could think it is the case... But you would be wrong!

They say they encrypt, but they use old stuff...

Take google as an example, when they pass to your device the private and public keys for the TOTP, they use HMAC-SHA1, which was basically first broken in 2005. Interested? Check here and here. You would think they take your security seriously 🤔. Well, think again!

They offer various MFAs, but most leak...

Take Microsoft as an example, who recently warned their users that their 2FA based on SMS or voice calls where the least secure MFA that exists. Interested again? Check here. You would think that they would remove the leaky MFAs and not allow their users the option of a leak 🤭. Well, think again!

They use best practice TOTP, but in fact not...

Take around half the 2FA/MFA vendors who provide TOTP for paid subscriptions and store your pivate key in their cloud for your "convenience", in case you lose your phone. Do yourself a favour and google search "cloud backup TOTP". See the long list of those who will leak your private key one day? You would think that that they would not store the 2FA alongside your password 😂😂😂 just in case the hacker will get both at the same time 🥳. Well, think again!

How to backup and restore a 2FA
