## Hash and verify the passwords { #hash-and-verify-the-passwords }

Import the tools we need from `pwdlib`.

Create a PasswordHash instance with recommended settings - it will be used for hashing and verifying passwords.

/// tip

pwdlib also supports the bcrypt hashing algorithm but does not include legacy algorithms - for working with outdated hashes, it is recommended to use the passlib library.
