Why no MD5

The browser crypto API deliberately does not implement MD5 or SHA-0, because both are broken for anything security related. We could ship our own implementation, and chose not to: a tool that makes a broken algorithm convenient is a tool that keeps it in use.

Hashing is not password storage

A plain SHA hash of a password is not secure storage, no matter which SHA variant. Passwords need a slow, salted function such as bcrypt or argon2, which is exactly what a fast hash is designed not to be.
