Passlib 1.7.0 support argon2 type hashing. I wanted to use it as Password hasing algorithm.

But sqlalchemy-utils generate VARBINARY(4294967331) field. It is too huge!

Size of PasswordType is depend on max_salt_size value and Argon2's max_salt_size in passlib impl is MAX_UINT32.

I think you write some notice on docs or make some arguments to PasswordType for limit salt size. Default salt size setting is 16 (argon2_cffi(passlib recommand it), passlib)

I used a workaround

import passlib.hash
passlib.hash.argon2.max_salt_size = 16

in the file where the models are defined.
