MONAI Label OAuth2 Resource Owner Credentials flow Grants req. long token access

[dean-taylor]

Signature has expired.
Using this method the authorisation token can not be renewed and requires user intervention when it expires.
The user needs to log out / deleting token and then manually log back in to acquire a new token.

WORKAROUND. Provide a very long lived authorisation token. This is poor practice and should be rectified ASAP.
