Access Log

From inside Salesforce 1, Administrators are able to see the list of the latest users who have tried to login to their Salesforce orgs and if the login attempt was successful or not.

Main features for Salesforce Administrators:

• See the error message associated with the failed user login attempts.

• Filter the list by Success or Fail Login attempts.

• Navigate directly from the list to the user record to get more details about the User
