How can I perform a Salesforce login as user?
My Profile is System Administrator in the Salesforce org(sandbox). Is there any way to login as any other User without the Grant access by the User?
Per the help article on the topic Salesforce login as user: https://help.salesforce.com/articleView?id=controlling_login_access.htm
From Setup, enter Login Access Policies in the Quick Find box, then select Login Access Policies.
To allow Salesforce admins to log in as any user in the org without first asking them to grant access, enable Administrators Can Log in as Any User.
