# Key Backup

In Wepin, if you wish to back up the key and utilize it in another wallet system, you can export the private key. Users must authenticate themselves to export the key and agree to the terms regarding responsibility. The returned key is provided as a mnemonic phrase, and please be informed that Wepin does not assume responsibility for the user's assets tied to the returned key.
