Question

I was finishing up a simple user login with Flask and flask-Bcrypt. However, when trying to login with a user that is stored in my database, I keep getting this error

I believe you are using python 3 and bcrypt0.7.1. first you have to delete the users in your database, then go to your models and add .decode('utf-8') to the generate_password_hash() method like so:

pw_hash = bcrypt.generate_password_hash(‘hunter2’).decode('utf-8')

Alternatively you can uninstall flask-bcrypt==0.7.1 and install flask-bcrypt==0.62. Make sure you delete the users from the tables before installing flask-bcrypt==0.62
