@teselia/otp

Accessible one-time code input for verification codes, shipped as a framework-agnostic Web Component. It looks like a row of cells but is one real text field, so paste, SMS and email autofill, password managers and screen readers all work. It meets WCAG 2.2 AA by default and submits the code to any native <form>.

Documentation and demo

• Digits by default, or letters and digits with type="alphanumeric". From 1 to 12 characters.
• Pasting 123 456 or 123-456 fills every cell. Full-width and Arabic-Indic digits are accepted too.
• autocomplete="one-time-code" by default, so the keyboard can offer codes from SMS and email.
• A real form control: required, validation messages, setCustomValidity() for server errors, reset, disabled fieldsets and Enter to submit.
• Optional autosubmit when the last character is entered, announced to everyone in advance.
• Keyboard-first: the keys of any text field, plus typing over a cell to replace it.
• Themeable with CSS custom properties, ::part() and :state().
