About the SHA-256 Generator
SHA-256 is the current default for integrity checking, certificate signing, blockchain work and content addressing. No practical attack against it is known.
Being fast is a virtue for checksums and a problem for passwords: a GPU can test billions of SHA-256 guesses per second. Passwords need a deliberately slow function such as Argon2id or bcrypt instead.

Is it free, and do I need an account?
Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
