Blocks uses two factor authentication as a second layer of security and user identification.  In addition to entering an email/password combination, a text will be sent to the user’s cell phone via SMS with a unique numerical code.  The user must enter the code on the login page to gain access to the site.

The code that is sent is good for 5 minutes. 

You should only set 2FA up with your own number. 

You should not share your 2FA code with anyone to allow them to log in to your account.
​
​How to change the two factor authentication number:  

For your own number: If you are logged in, you can click on the lego head in the upper right hand corner of your Blocks window to make this change. 

For another user: Impersonate the user and click the Lego head in the upper right hand corner of your Blocks window to make this change*.  

*This will send a verification code to the new phone number.  If you are not able to get this code from the user, send us a support request and we can make this change on our end.
