Welcome to AppsFlyer

At a glance: Learn what mobile advertising attribution is and how AppsFlyer helps marketers pinpoint their targeting, optimize their ad spend, and boost ROI. 

What is app attribution?

App attribution determines which campaigns, partners, and channels drive your app installs and post-install events, such as in-app purchases. Marketers rely on these insights to measure and optimize marketing activities for both user acquisition and retargeting campaigns.

What can you do with AppsFlyer?

At a glance: How to log in to your account for the first time and how to switch between your accounts.

First login

When your user is first created, you get an email invitation to activate your account. Once activated, you can log in and the account becomes active. Note that the activation link is valid for 48 hours.

There are a number of ways to log into your AppsFlyer account:

  • Using credentials: Email and password
  • Login with Google: Log in using your Google Account
  • Login using SSO


If your administrator configured a two-factor authentication (2FA) for your account, you'll be asked to verify the login using another authentication method. 

Switch between accounts

If you have more than one account, when logging into one of them you're presented with all your associated accounts. Select the account you'd like to log into. Once you're in one account you can switch to another account.

To switch between accounts:

  1. Log out of your current account: From the top bar, open the account menu (email address dropdown) > Logout.
  2. Log in and select a different account from your list of associated accounts.
