# What is Mnemonic Login?

A mnemonic phrase is a string of 12 randomly generated words used to protect your account and assets.

In Luffa, mnemonic phrases from any blockchain can be used to log in, and we do not collect personal information such as phone numbers or email addresses, ensuring complete anonymity. The mnemonic phrase generates a public-private key pair, which is used for encrypting and decrypting messages and securing your digital assets.

Therefore, it is crucial to properly back up and protect your mnemonic phrase to prevent loss or leakage.
