Description

This article describes how to recover login credentials after upgrading to v7.4.7 to access the GUI.
Scope FortiGate.
Solution
Certain firewalls are no longer accessible via GUI with admin credentials after the firmware update to v7.4.7, and starting with v7.6.x.
 
There may be several reasons why authentication is unsuccessful.
  1. Try to clear the browser cache or use a different browser.
  2. Ensure the password is correct, verify that the keyboard layout has not changed, or try copying the password in plain text from a text file.

If the above requirements are met, resetting the user password helps to provide GUI access again.
 
Option 1:

Create a new user using the credentials that worked before the upgrade:

  • Connection through the console cable.
  • It is necessary to perform the following password recovery steps to reset the password and be able to access the FortiGate again through the GUI.

 

Steps:

     

     LAB-01# conf sys admin
     LAB-01 (admin)# edit admin
     LAB-01 (admin)# set password xxxxxx 
     LAB-01 (admin)# end
     LAB-01#

 

Change the password (minimum of four characters). Now log in again via GUI to the FortiGate using the new password that has just been modified.

 

Option 2:

Create a user through FortiCloud. Subscription required: Technical Tip: Reset FortiGate admin password via FortiGate Cloud.

 

Option 3:

If there is only one admin account configured and the admin is unable to log into the GUI to change the password, password recovery needs to be done using this documentation: Technical Tip: Resetting a lost admin password.

Option 4:

It is possible to roll back the upgrade from the BIOS by booting off the backup partition. This method requires access to the console. For instructions on how to rollback to the previous firmware version through console, see Technical Tip: Boot the backup firmware and config via console .
