Password Strength Validation Form for Ark UI

A password that needs 8 characters, mixed case, a number, and a symbol, plus a matching confirmation.

Password must be 8 characters with an uppercase letter, a lowercase letter, a number, and a symbol. Confirm Password has to match, or it shows Passwords don't match.

Use it when a new account needs a strong password. A length check alone fits a Password Input. In React, Ark UI does not score the password.

FAQ

Which password rules run, and which message shows?

.min(8, "Password must be at least 8 characters"), then regexes for [A-Z], [a-z], [0-9] and [^A-Za-z0-9], each with its own message. The FieldError shows the first one that fails, in that order.

How are the two passwords compared?

The object's refine checks data.password === data.confirmPassword and fails with "Passwords don't match" on path: ["confirmPassword"], so it shows under Confirm Password. confirmPassword itself is just z.string().

Where are the rules written before an error?

The password's FieldDescription says "Must contain uppercase, lowercase, number, and special character." Confirm Password's says "Re-enter your password to confirm."

Are both fields masked?

Yes. Both Inputs are type="password", with the placeholders "Enter password" and "Confirm password", and field spread onto them.

What is submitted for an empty form?

Nothing. defaultValues sets both strings to "", so the length rule fails first and "Password must be at least 8 characters" shows before any character-class message.

What does Create Account receive?

Create Account is a type="submit" button. form.handleSubmit(onSubmit) calls onSubmit with both strings only after every rule and the match pass, and the demo logs them.
