Google oAuth

[AdventurePandah]

Hi there,

I just had a exam for development. In this exam they asked to check a snipped code and say if the Two factor authentication is applied succesfully.

Instead of using the Google authenticator or something like that, they used Google oAuth. 

I always thought that Google oAuth isn't a 2-factor authentication. Is Google oAuth a Two Factor Authentication?

Regards,

Bas

Hi Bas,

OAuth is a method for secure authorization of requests between websites.

It uses a method where, as a site visitor, you agree that a site has access to the information stored on another website.

See https://oauth.net

If you are looking for an example of 2FA, in our Zotonic CMS we implement 2FA in mod_auth2fa.

https://github.com/zotonic/zotonic/tree/master/apps/zotonic_mod_auth2fa

It uses TOTP (as supported by Google Authenticator et al) and displays the QR code for the user to scan.

Cheers, Marc
