How to remove broken SAML configuration on AEM Author or a bypass url?

We have configured a SAML configuration on AEM Author. The integration isn't working but we are locked out of accessing AEM Author. The SAML bypass url doesn't seem to be working as well.

Our redirect url isn't correct so we need to remove the SAML config.The SAML bypass url shows AEM Author login page, but does not let us go beyond. 

Configuration:

1. Create a Trust Store

2. Updated Authentication Service user adding a Keystore

3. Created a new SAML configuration in ConfigMgr.

By pass url we are using: http://<server>:4502/libs/granite/core/content/login.html

How can we solve this?
