Masked OTP Input Input OTP for Svelte

A six-digit code field that stays blurred until an eye button is pressed, with a note about showing the code.

UI library: Ark UI

Six boxes sit blurred beside an eye button. A line under them says Toggle visibility to show/hide the entered code.

Blur the code when it might be read over someone's shoulder. A Password Input fits a password, not a one-time code. In Svelte, Ark UI moves to the next box as you type.

FAQ

How is the code hidden?

The field's wrapper gets blur-sm and select-none while the code is hidden. The digits are still typed normally; they're just unreadable on screen.

How does the eye button work?

Whether the code is shown lives in state. The ghost Button at size icon-md flips it and swaps EyeIcon for EyeOffIcon.

How do screen readers know what the button does?

Its aria-label follows the state: Show code while hidden, Hide code while shown. The icons have aria-hidden.

Can the slots show dots instead?

Yes. Set mask on InputOTP and each slot shows a dot, like a password field; toggle it from the same state as the blur.

Is the code hidden from screen readers too?

No. The blur is visual, so assistive technology still reads the digits. That's usually right: the person typing is the one listening.

How is the value kept?

In state, written on every change. The value is an array of strings, one per slot, and each change arrives as details.value.
