Sign-in codes don't arrive
The app sends sign-in codes through Digits and the SMS or WhatsApp gateway configured on your website. Most problems are in that chain.
- 1
Try signing in on your website
Use the same phone number to sign in on your website. If the code doesn’t arrive there either, the problem is in Digits or your gateway, not in the app.
- 2
Check your gateway
Check your gateway balance, your sender name or approved message template, and the gateway’s delivery logs.

Check the phone number
Students must enter their number with the right country code. Compare the number with the one in the student’s WordPress account.

Wait a few minutes
Codes are rate limited per phone number and per network to stop abuse. After several attempts, a student has to wait before asking for a new code.
