Time for a TIL post – mainly so I find this information later!
I’ve been ensuring that 2 factor authentication is up and running for the org that I am currently working in and wanted to make sure that the SMS method was the primary second factor, rather than email. However, there’s no way to force this to happen without the users having verified mobile numbers on their profiles. Getting everyone to enter and verify their numbers was going to be a pain.
Then I stumbled across this knowledge article: How to verify a valid mobile number. This shows us that if we update a user’s profile with their mobile number is specific format it is considered to be verified! This made my job a whole bunch easier and allowed me to update everyone’s profile with their mobile numbers and have it be used as the second factor in my two factor auth setup. All without the user needing to do anything. Easy!
