As an admin, there are different ways to access your portal as one of your users:
You can impersonate any user by accessing your portal using their login credentials. Go to the table configured as your Users Table in your Airtable account and use the value from the login fields.
If you have a login formula field configured, you can use it on your browser to directly access the respective users' portal view.
You can change the login fields and use a field with a value you know.
💡 If your login has any form of verification in place, you can disable it briefly when logging in to their account and then enable it once again.
