Firstly, don't panic: Your Yoti is protected by multi factor authentication. It’s linked to your phone, protected by a PIN that only you know and linked to your face. Hopefully, you've also got a lock screen on your phone, with a strong code or fingerprint!
So if you lose your phone, somebody else would not be able to use your Yoti app as they would need to know your PIN or have the same face as you.
If you get a new phone and would like to put your Yoti onto it, you will need to get in contact with us and, after confirming who you are, we will freeze your old account and allow you to create a new one. We are working on making this process smoother in the near future.
