-* Login using username and password will create Splunk token internally.
-* Login using Credentials (username & password) OR directly using Splunk token are similar.
-* In above two approaches, there is one limitation that expiration time of Splunk token cannot be extended. User has to re-login every time when token expires.
-* To overcome this limitation, **Bearer** token is used instead of Splunk token.
-* In **Bearer** token, user has a provision to set token expiration time. Splunk allows user to set relative/absolute time for token expiration.
-* In other words, **Bearer** token is configurable whereas Splunk token cannot be configured.
