One authenticator app for multiple accounts?
Hopefully people are becoming more familiar with the new two step verification, so I wanted to ask:
1. If you use say Google authenticator with 10 different Amazon accounts are any of them going to get linked this way?
2. They MAKE you use a phone number at the same time you first set up two factor verification, but are there any circumstances in future where they will force you to use the phone number instead of the app as the verification? Or will you always be able to use the app?
