Applovin uses a service called “Authy” to manage 2FA.
If you have issues entering your number immediately after you sign up:
- Note that VOIP phone numbers are not supported.
- Make sure you don’t have any ad-blocker enabled.
- Try using a different browser and a different device.
- After choosing the right country, type in the phone number as you would call it locally (no additional country code), and remove any spaces or dashes.
If you have issues receiving an SMS and you have previously successfully logged in:
- Make sure you don’t have any ad-blocker enabled.
- Try using a different browser and a different device.
- If you received multiple codes, wait one hour and try again.
- Try using the Authy app from authy.com (instructions below).
If you are having issues receiving an SMS and you have NEVER successfully logged in:
- Make sure you don’t have any ad-blocker enabled.
- Try using a different browser and a different device.
- Try using the Authy app from authy.com (Instructions below).
- Open a support ticket at our Developer Support portal to confirm that you entered the correct number when you signed up. In your support ticket, please include the phone number you expect to have registered.
- If you have never logged in you can open a support ticket at our Developer Support portal to reset the number associated with your account. (Note: The support team can only help in this way if you have never logged in. We are unable to change your number or speed up Authy phone number change requests.)
Changing your phone number:
If the phone number that you use for two-factor authentication changes, follow the instructions here: “Request to Change Your Phone Number”. Make sure to follow all steps and to approve the number update in the email received by the email address associated with your AppLovin account. This process takes several days, which allows the holder of the old phone number to cancel the process (this prevents malicious actors from gaining access).
To transfer your AppLovin account to another person, open a ticket in which you request AppLovin to update the number associated with your account.
Using the Authy app:
If you are unable to consistently receive SMS from Authy, the Authy app may be the best option for you. You will only need to authenticate the app once, and then you can use the app to generate the codes to input into AppLovin. You can also authenticate the app with a phone call. You can get the Authy app from authy.com.
There will automatically be an AppLovin section within the Authy app if you authenticate the app by using the same phone number that you used when you signed up with AppLovin.
You can also use the Authy app to quickly change the number associated with your account (assuming you have already authenticated the app with your old phone number).
