DeletedUser26 If the autofill in your password manager doesn’t work, most people’s instinct is to just manually copy/paste the password and totp code in.
Then that's the fault of most people, and they should make at least some attempt to stop being so passive/carefree in their security.
The autofill in your password manager is a convenience feature not a security feature.
Except it can be a security feature for those who know to use it as one. Just because better security features exist does not mean it isn't/can't be one.
