Info would be useful about salt in documentation, werkzeug version should be fixed.

I've faced some issue when I've tried to use the server:

It was not clear for me how to generate the salt.
I've ended up using bcrypt.genSalt() method from a local python env. It looked something like: $2a$10$3rG14pYiZyUNs0Z9FfFJ5u

Another issue was that dash and werkzeug python libraries are not always compatible, so I had to add werkzeug==2.0.3 in requirement.txt

Besides that thank you for sharing the project!
