How to remove 2FA for admin using CLI

This article provide information on how to remove 2-Factor Authentication for Administrator login using the CLI.

Many user login Authentication requires one-time password .SonicOS 6.5.3.1 or latest provides additional layer of security with Time-Based One Time Password (TOTP). If the system time is wrong and NTP server time is mismatching, then we cannot login to the firewall and will get error like "Please try again later ".
You may need to use the CLI for the following reasons:
* When you don't have access to firewall GUI to disable TOTP.
* When you get "Please try again later " message even after you enter the One time password.

1. Make sure SSH is enabled on the X0 interface.
2. Open Putty
   
3. Set Baud = 115200
   Date bits = 8.
   Parity = None.
   Stop bits = 1.
   Flow Control= None.
   
4. Refer this article to login to the sonicwall using putty, https://www.sonicwall.com/support/knowledge-base/how-can-i-login-to-the-appliance-using-the-command-line-interface-cli/170505641032025/.
5. Run the following commands
   >Configure
   >Administration
   >No admin one-time-password
   >Commit
   >Exit
   
6. These 5 commands will be used to disable the TOTP for the Admin.
7. Now we can login to the firewall without providing the one time password.
8. Check the System time if it set properly based on your time zone.
   
9. After verifying the system time then you can enable the TOTP for admin login.
