OtpField is a Vaadin Flow input field for a fixed-length verification code. It renders one slot per character and behaves like any other input field, so it works with Binder out of the box. ## Features * One visual slot per character, with the active slot following the caret. * Complete keyboard, paste, drop and `autocomplete="one-time-code"` autofill behaviour, with no application-side glue code. * Configurable length (1–24, default 6), accepted characters through `allowedCharPattern` (numeric by default), case conversion, per-slot placeholder and masking. * `Binder` integration with built-in *required* and *incomplete* constraints, and an `OtpCompleteEvent` that fires when the code reaches its full length. * Accessible: one tab stop, announced as a single field, and usable with a screen reader. * Themeable through documented CSS custom properties and shadow parts, under base styles, Aura and Lumo. #### Found a bug or have a suggestion?
