Password Change Re-aunthentication Issues

[amycapel1112]

On three separate occasions spotify has randomly logged me out and told me my password was incorrect (when it wasn't) - I recently made an app which connects to the spotify API which I think must be something to do with the issues as it didn't happen previously. Anyway every time this happens I'm forced to change my password and the app I made breaks - I have a little reaunthenticate function but it seems very random whether or not it works - the last couple of times this has happened I have eventually got it to reauthenticate, but the same code just doesn't work the next time - I just keep getting a "This site can't be reached localhost refused to connect error message". Does anyone know what's going on here and how I can easily reauthenticate my app after a password change? Or ideally how to stop having to change my password!

If you have authenticated an app, you should have a token (including refresh token), and should not need to use the password. Try looking at the documentation on Authorization.
