1)The passphrase of a Pi Network wallet consists of 24 words. If you can only remember 22 or 23 words, you can use this tool to recover the missing ones.

2) If your Pi wallet’s passphrase has been compromised, for example, if you accidentally entered the passphrase on fraudulent websites, and there is still locked Pi in your wallet that hasn't reached its unlock time, the hacker will steal your Pi once it is unlocked. When the Pi becomes available for withdrawal, the hacker may immediately transfer your Pi to their wallet using software tools. You can use this tool to compete with the hacker for the locked Pi.
