10# Vault Agent Auto-Auth JWT Method
11
12The `jwt` method reads in a JWT from a file and sends it to the [JWT Auth
13method](https://www.vaultproject.io/docs/auth/jwt.html). Since JWTs often have
14limited lifetime, it constantly watches for a new JWT to be written, and when
15found it will immediately ingress this value, delete the file, and use the new
16JWT to perform a reauthentication.
