# One-Tap Autofill Authentication Templates One-tap autofill authentication templates allow you to send a one-time password or code along with an one-tap autofill button to your users. When a WhatsApp user taps the autofill button, the WhatsApp client triggers an activity which opens your app and delivers it the password or code.
One-tap autofill button authentication templates consist of: * Preset text: *\ is your verification code.* * An optional security disclaimer: *For your security, do not share this code.* * An optional expiration warning (optional): *This code expires in \ minutes.* * A one-tap autofill button. {% hint style="warning" %} One-tap autofill buttons are only supported on Android. If you send an authentication template to a WhatsApp user who is using a non-Android device, the WhatsApp client will display a copy code button instead. URLs, media, and emojis are not supported. {% endhint %} ## Template Creation You can use the WABA API to create One-tap autofill authentication templates. Alternatively, users can also create it using the WhatsApp Business Manager. #### In the API Use the create template [endpoint](https://docs.360dialog.com/docs/messaging-api/api-reference/templates#post-v1-configs-templates) and assemble the components in the request: The message template name field is limited to 512 characters.
