Text message sign-in codes (SMS)

authto.it sign-in codes is the text-message program of authto.it, a hosted sign-in service of Scaled Apps LLC. Businesses use authto.it to let people sign in to their websites with a one-time code instead of a password. The sign-in page, at letme.authto.it, shows the business's name and logo.

A code is texted only when the person signing in asks for it on that page and agrees, as shown below. Texts are only ever sign-in codes, never marketing.

How people opt in

  1. On a website that uses authto.it, a person chooses to sign in and is taken to the sign-in page.
  2. They choose text message, enter their mobile number and tick the consent box below it. The box is never ticked in advance, and no code is texted without it.
  3. We text one sign-in code to the number. Another is sent only if they ask again.
  4. Replying STOP at any time ends all texts from authto.it's number to that number. Replying START from the same phone turns them back on. (Signing in with an email address instead would count as a different person on that website.)

The consent box reads, with the website's name in place of Example Co:

When the box is ticked we record the number, the website, the exact words agreed to, the time and a one-way hash of the IP address.

What we send

  • Type: one-time sign-in codes only, each valid 10 minutes and usable once.
  • Frequency: one message each time the person asks for a code; nothing otherwise. Requests are limited per number.
  • Cost: free from us. Message and data rates may apply from your carrier.

Sample message:

123456 is your Example Co sign-in code. It expires in 10 minutes.
