In TYPO3, an editor's work is done via the backend and having a working backend account is critical.
Enter your domain name into the address bar of your internet browser and
append "/typo3" to it to get to the "log in" page of your site.
Troubleshooting: Forgot password for backend login¶
Click on Forgot your password?
Go to the backend login page and select Forgot your password?.
Enter your email address
Use the exact email address you used during registration.
Open the email
Note that you will get the following page even if the email you entered was not found. This is due to the fact that the system will not disclose information about any registered email addresses.
If you do not receive the email, check your spam folder and double-check the email address is correct.
Enter the new password
After you clicked on the password recovery link in the email you received you can enter a new password. Always use a secure password.
