What is Crazypass on monerujo? Isn't the Mnemonic phrase sufficient to recover the address?
IIRC, the unfortunately named CrAzYpass is basically the real password that encrypts your wallet. But because it's a bit long to remember the user can define their own, easy to remember password. This user-password is just used to lock the actual encryption-password (CrAzYpass) inside the secure enclave of the phone.
If you ever were to move your wallet to another phone, then you CANNOT unlock it with your user-defined password, because that was just used to secure the actual encryption key. Instead you would have to unlock the wallet with the actual encryption key, which is the CrAzYpass. (So be sure to store it in a secure place!)
Afterwards you can give the wallet a user-defined password again, for a more convenient access.
This image explains it pretty well I think: IMAGE
