There's a few issues with managing credentials. The first is, there is
no way to remove a credential. This is essential to TOTP as you may end
up with a lost or obsolete device.

THe 2nd is that for TOTP, you will want to check every device on a
credential validation rather than just one:

Our own VPN allows me to set up multiple tokens. I have one on my
iphone and ipad just in case I lose one or the other. OUr VPN allows me
to use either to login in.
