Please note that Pow has many guides included in the docs.
Password breach lookup and other password validation rules
September 14, 2019
By default Pow has a lax requirement of minimum 10 characters based on NIST 800-132, but there are many more types of validations you can use to ensure users don’t rely on weak passwords.
Dealing with multiple user schemas
September 12, 2019
Pow can handle multiple user schemas out-of-the-box in umbrella projects, or can be configured to handle it in the same Phoenix endpoint.
