What should I do when I receive a message stating that my registration has been disabled because the Binance API key is invalid?

If for some reason Binance has invalidated your API key, Anny can't work properly and deactivates the user.

You just need to go to Binance, create a new API key and update your Anny's account with the new one.

To change the API, access your profile (in the upper right corner), click on settings and then on exchanges.
