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. 

Using multiple accounts

Users can exist in multiple accounts with different roles and permissions. They can navigate between their accounts without the need to re-enter credentials.


  • Switching between accounts and changing the primary account is supported for all login methods: Username and password, 2FA, and Single Sign-On (SSO).
  • At this stage, switching between accounts is restricted to advertiser accounts only.

Primary account

The primary account is the initial account that was created and acts as the default login account. You can set any other account to be primary.


To change the primary account:

  1. From the menu bar, select the email address dropdown > Switch accounts.
  2. Access the list of your accounts: Select All accounts (x), with x indicating the total number of accounts.
  3. In the My accounts dialog, click the 3 dots menu icon for the account to be set as primary, then select Set as primary. A message confirms the account change.

Switch between accounts

  1. From the menu bar, select the email address dropdown > Switch accounts.
  2. Select the account to log in to.
