Let me share some troubleshooting steps that can help your users access their accounts, Doaa.
2-factor authentication is a security measure designed to confirm the identity of a user signing into an account using their login ID and password. For security, it's not recommended to disable 2-factor authentication.
If the user didn’t get a text, email, or phone call with the verification code, please know it takes a couple of minutes for the code to arrive. In addition, they can also perform the following steps:
- Check your junk mail or spam folder to see if the email went there.
- Check all email addresses you might've used to sign up for your account.
- Unblock or add Do_not_reply@intuit.com as an approved sender in your email app.
- Select the I didn’t get a text, I didn’t get an email, or I didn’t get a phone call link on the product sign-in page to get a new code.
- Make sure to allow or unblock our numbers 88811 and 97962 on your iOS or Android device.
