If you're using AutoWikiBrowser (AWB), make sure you've done the following:
Set up a bot password for your bot account (see Using Special:BotPasswords for more info). The bot password name you choose (e.g., ReBot2@AWB) and the auto-generated password will be used for logging into AWB later, so set them aside somewhere. If you lose the password, you can always generate a new one via Special:BotPasswords.
Optional: Give your bot account the appropriate role (e.g., Content Moderator or Administrator) depending on the editing permissions set in the previous step. Just like a regular user, your bot will not be able to edit protected pages or delete anything unless you give it the proper user rights.
To use your bot in AWB:
Download and install AWB on your computer (see this section on the help page).
Once it's downloaded, launch the program.
Go to Options → Preferences → Site
In the Project dropdown, select fandom.
In the text field that appears, type the subdomain of your wiki (e.g., imposters-n-roles).
Click OK to save your changes.
Go to File → Log in/Profiles...
Under Quick Login, type in the Username that was generated via Special:BotPasswords (e.g., ReBot2@AWB) and the randomly generated Password it gave you.
Check the Save this account box to make logging in again easier.
Click Login.
If the login was successful, you will see your bot account listed in the bottom-right corner of the screen in green.
For help on creating a list of pages and starting the bot, see the help page. There's also an in-depth manual on Wikipedia, which breaks down each section.
