## Used by methods

- [IRPCLogin.ChangePassword](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLogin/ChangePassword/index.md): Changes the M-Files password of the logged-in account.
- [IRPCLogin.GetPublicKey](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLogin/GetPublicKey/index.md): Gets the server's RSA public key, for encrypting secrets that a client sends to the server.
- [IRPCLogin.GetPublicKeyAnonymous](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLogin/GetPublicKeyAnonymous/index.md): Gets the server's RSA public key without a session, for encrypting authentication data before login.
- [IRPCLoginsAdmin.GetPasswordHash](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLoginsAdmin/GetPasswordHash/index.md): Gets the encrypted password hash of an M-Files login, for copying the password to another server with [SetPasswordHash](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLoginsAdmin/SetPasswordHash/index.md).
- [IRPCLoginsAdmin.ResetPassword](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLoginsAdmin/ResetPassword/index.md): Completes the "forgot password" flow: sets a new password for a login with the values from the password reset link.
- [IRPCVaultLoginsAdmin.GetVaultLoginPasswordHash](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCVaultLoginsAdmin/GetVaultLoginPasswordHash/index.md): Reads the password hash of a vault login, encrypted with a public key that the caller supplies.
- [IRPCVaultLoginsAdmin.ResetVaultLoginPassword](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCVaultLoginsAdmin/ResetVaultLoginPassword/index.md): Sets a new password for a vault login, authorized by a password reset link.
