I cant log into my Xiaomi Mi Mix

I changed my password some days ago of my Xiaomi Mi Mix phone and since then I have been able to log into my phone with this password. It also has the fingerprint sensor activated. I just noticed today that I can no longer use any of the options to log into my phone anymore. I even tried using the old password but I keep getting the same error and cant log into my phone. Has anyone here experienced this kind of thing before?

Kindly help
