[ncc-services-wg] Adding more than one 2FA authenticator to your account

Hi.

Now than 2FA is mandatory when logging in on the RIPE website, it would be 
nice if we could add more than one 2FA authenticator / TOTP generator to 
our account and use either when logging in.

For example using either Authy on your phone or Yubico Authenticator on 
your computer.

That way, if you lose your phone, you can still log in from your computer 
and revoke access from the Authy app, until you get a new phone and set up 
a new 2FA authenticator on it.

On some other sites where you can use multiple 2FA authenticators, they 
even show which authenticator was used the last N times you logged in. It 
makes it very easy to spot, if someone has gained access to your 2FA 
authenticator secrets and is actively using that access.

I hope, you'll consider the idea. Thanks in advance...
