This topic explains how to use the same email address for multiple LaunchDarkly accounts.
Using the same email across multiple accounts enables you to:
To create a new account using an email address already associated with a LaunchDarkly account:
You must use your email address to join a LaunchDarkly account. The email address you enter during initial setup is case sensitive. Future attempts to log in with that email address will fail if you use different casing.
For example, if you sign up as example@your-work-email.com and later log in as EXAMPLE@Your-Work-Email.com, the login attempt will fail.
You can create up to three trial accounts using the same email address. If you require additional trial accounts, start a Support ticket.
If you already have multiple accounts, you can update them to use the same email address.
Here’s how:
Your changes are confirmed. Test them by logging out and logging back in with your updated email address.
You can repeat this procedure for other existing accounts for which you also want to use the same email address.
The authentication method is unique to each account. This includes your password, the account settings for single sign-on (SSO), and whether multi-factor authentication (MFA) is enabled. Only the email address is the same across multiple accounts.
If you use the same email address with multiple LaunchDarkly accounts and one of those accounts uses Google OAuth as the SSO provider, you must use the “Continue with Google” button to sign in to your accounts.
To sign in to LaunchDarkly using an email address that is associated with multiple accounts:
Enter the email address associated with your LaunchDarkly accounts. The system will redirect you to a page that lists all of the organizations associated with that email address.
Click on an organization to continue.
Authenticate your account:
If LaunchDarkly doesn’t recognize the device you’re signing in from, it will send a verification link to your email. Click Verify email to confirm your identity. You are directed to a “Trust this browser?” page.
If you want to trust the browser and skip identity verification for the next 30 days, click Trust this browser. Otherwise, click Don’t trust.
Select which organization to log in to.
Enter your password.
You are now logged in to your selected organization.
To switch to another organization while signed in:

When you sign in to a second organization, LaunchDarkly signs you out of the first organization. You can only be signed in to one organization at a time.
There are several reasons your organization may not be listed during the sign in process:
Deleting a trial account permanently removes all account data, including projects, environments, flags, and members. If your application still includes calls to any of the LaunchDarkly SDKs, the SDK will fail to authenticate and any feature flag evaluation will serve the fallback value defined in your code.
Please be certain.
To delete a trial account:
yes in the Confirm field.Your trial account is now deleted.
