Hola Amilcar,
The easiest solution will be to create a new administrator's account, log in with that, and then either update your old password and delete the temporary admin account, or delete your old account and use the new one instead.
You can create a new administrator's account via the command-line with the following task:
- php symfony tools:add-superuser name
Where name in the example above is the new username of the account you would like to create. The task will then prompt you for an email address and a password. See:
After that, you can log in with the new administrator account. Now you can either change your old password or delete your old account and use this new one instead. Either way, go to Admin > Users next. For more information on managing user accounts, see:
Cheers,
