Fingerprint deletes automatic TB 2016

[Super Xander]

Hello
I don't know why, but my MacBook Pro deletes the fingerprint automatic every second month or so.
Do anyone have the same problem or know why it does so?

It's a security measure. Just like passwords, it's a good idea to change your fingerprint on a regular basis.
