FAQs
1. Why can't I see the Smart Sign-in option in OneAuth?
|
Possible Reasons
|
Solution
|
|
You are using an outdated version of OneAuth.
|
Update to v3.1 or higher.
|
|
For versions that use 'Smart sign-in' instead of 'Scan any QR'
|
|
|

|
Contact your administrator for clarification.
|
|
Restrict Sign-in is enabled for your account.
|
Disable it to use Smart Sign-in.
|
2. Why am I getting a 'Smart Sign-in not allowed' error in OneAuth?
Possible Reasons | Solution |
Your organization has enforced other MFA modes (such as SMS based OTP, Security Key, or 2FA Authenticator) and has not included OneAuth as an allowed mode. | Your organization needs to allow OneAuth as an MFA mode for you to use Smart Sign-in. Contact your administrator for further clarification. |
Your account is MFA-enabled, but this device is not an MFA-enabled device for your account. | If you don’t have access to your OneAuth MFA-enabled Primary device, you can set another signed-in mobile device as your primary or secondary MFA device in OneAuth.
If both primary and secondary devices are inaccessible, repeat this process on another signed-in device to use Smart sign-in. |
IP restriction is enabled, and you are trying to sign in from a different IP address than configured. | Sign in from the allowed IP address or disable the restriction. For organizational restrictions, contact your administrator. |
3. Will enforced password changes by my organization affect Smart Sign-in?
No, Smart Sign-in will not be affected. However, if you sign in using your password instead of Smart Sign-in, you will need to change it when required by your organization.
4. Can I use Smart Sign-in if my mobile device is on a different IP address than the IP restriction enabled for my account?
No, both your mobile device and browser must be on the configured IP address. Smart Sign-in will not work otherwise.
