Authentication succeeded after Locked my MBP via find my on my iPhone

I was gonna test the functionality of Mark as Lost, and activated the lock on my Mac although I did not lose it… Then, I typed in my password on my MBP to unlock it. Now it is spinning the rainbow with a view saying:

macOS Recovery

Authentication Succeeded.

The rainbow has been spinning for an hour… did I screw my MBP? Would I lose my data?
