Access Tokens have been reset

As a part of Twitch’s password and connections reset, the access tokens used for the bot and other services has been reset.

You have received an email from Twitch explaining why this has happened, it is basically due to unauthorized access by hackers on March 3rd and as a safety measure they reset everyone’s passwords and connections as precaution steps.
Update: This has been posted on Twitch’s blog, click here for more information.

To use the bot again you will have to reset the password of both your account and the bot’s and generate tokens again the same way you have done so initially.
