Microsoft authenticator app

Hi

Just a little confused about the OTP codes for microsoft account, how comes its an 8 digit one time code in this app?

Other account are using 6 digits.

It seems to use the passwordless method to sign into MS account, so Im wondering where, if ever I would require the 8 digit code?

Signing into new devices/places. It will ask for your login details then the code.

It's a bit weird, my decades old Hotmail has an 8 digit OTP while recent O365 admin accounts are 6 digits. Didn't actually realise how much I use Authenticator!

I see, been using google authenticator, but changed to MS as it has the backup feature. Not tried signing into a new device yet, but it's pretty neat how it just requests you to approve the login via your phone using passcode or face ID.
