Esper login: user cannot identify username or retrieve password — guide user to invitation email and tenant admin

Android

If you can't log in to Esper because you don't know your username or password, this guide will help you regain access. Your Esper username is the email address associated with your account, and Esper Support cannot retrieve or reset passwords for security reasons.

Before you begin

Understand how Esper login works:

• Your username is the email address to which your invitation was sent—there is no separate username field.
• You must complete the invitation flow by clicking the Accept Invitation link in your invitation email to set up your account.
• Navigating directly to your tenant URL without completing the invitation may cause login to fail or log you into the wrong account.

Step 1: Locate your invitation email

Search your email inbox (including spam and promotions folders) for an email from Esper or your organization containing an Accept Invitation link. The email address this invitation was sent to is your Esper username.

Step 2: Complete your first login

If this is your first time logging in:

1. Click the Accept Invitation link in the email.
2. Follow the prompts to complete account setup.
3. Do not navigate directly to your tenant URL—you must complete the invitation flow first.

Step 3: If you have a previous Esper account

If you previously created an Esper trial account or have another Esper tenant under the same email address:

1. Click the Accept Invitation link in the new invitation email.
2. On the login screen, select Log in (shown below the Continue button).
3. Do not select Sign up, as this will create a duplicate account.

Step 4: Clear browser cache if login still fails

Cached sessions or automatic sign-ins can interfere with logging into the correct account:

1. Open an incognito or private browser window.
2. Click the Accept Invitation link again.
3. Complete login in the fresh browser session.

Step 5: Confirm the correct email with your tenant admin

If you have multiple email addresses and are unsure which was invited:

1. Ask your tenant administrator to check which email address was invited.
2. They can verify this in the Esper Console at Console → Manage → Users.
3. Once confirmed, use that email address to locate the correct invitation.

If your invitation link has expired

If your invitation link no longer works:

1. Contact your tenant administrator.
2. Ask them to resend your invitation from Console → Manage → Users → [Your Name] → Resend Invitation.
3. Check your email for the new invitation and click the link to proceed.

Important security information

Esper Support cannot view, reset, or share your password under any circumstances. This is a security measure to protect your account. Password recovery is handled through the invitation email and account setup process only.
