Social sign-in created a second account instead of logging me in

TL;DR — If social sign-in created a second account, the most common reason is that the social provider returned a different email address or a different provider identity than the account you already had. Start by checking the email on both accounts and the linked sign-in methods in your account settings; the usual fix is to sign in to the original account first, then link the social provider there, or ask support to merge the two accounts. Reading time: ~6 min

The scenario

It is a normal Tuesday afternoon: you click Continue with Google because you are already signed in on your laptop, expecting to land in your usual workspace. Instead, the app opens a fresh profile, your projects are missing, and your name or avatar looks slightly different. You sign out, try your password login, and suddenly your old data is back — but only on that login method. Now you have two accounts that both seem to belong to you, and you are not sure which one your subscription, history, or team access is attached to.

Symptoms

• After clicking a social sign-in button, you land in an empty or new-looking account.
• Your usual projects, invoices, team memberships, or saved settings are missing.
• You can access one account with email/password, but a different account with Continue with Google, Continue with Apple, or Continue with Microsoft.
• The profile page shows a different email address than you expected, such as:

jane.doe@gmail.com

instead of:

jane@company.com

• Apple sign-in may show a private relay address like:

8f3c1a2b4d@privaterelay.appleid.com

• You may see one account marked as verified and the other not verified.
• Team invitations, billing, or purchase history appear on only one of the two accounts.
• In some apps, the login screen briefly shows a message like:

Account created successfully

or:

Welcome! Let's finish setting up your profile.

when you expected a normal sign-in.

Likely causes

Step-by-step diagnosis

[You] ---- 1. click social sign-in ----> [App]
[App] ---- 2. redirect ----> [Social provider]
[Social provider] ---- 3. return email + provider ID ----> [App]
[App] ---- 4. match existing user? ----> [Account record]
[Account record] ---- 5a. match found ----> [Existing account]
[Account record] ---- 5b. no match ----> [Second account created]

1. Check which email is on the new account. Go to Account menu → Profile or Settings → Account in the app while signed into the unexpected account. If the email is different from your usual login email, even slightly, this is your problem. Jump to Fixes → Social provider returned a different email than your original account.

2. Check whether the address is an Apple private relay. In the same profile screen, look for an address ending in:

privaterelay.appleid.com

If yes, this is your problem. Jump to Fixes → Apple "Hide My Email" created a relay address.

1. Sign out and sign back in with your original method. Use the method that definitely reaches your old data, usually Email + Password. Then go to Settings → Security or Settings → Connected accounts. If the social provider you just used is not listed as linked, this is your problem. Jump to Fixes → Your original account was created with email/password and the social login was never linked.

2. Compare linked providers on both accounts. On the old account and the new account, open Settings → Security / Connected accounts. If one account shows Google linked and the other shows Microsoft linked, or one shows no linked providers at all, this is your problem. Jump to Fixes → You used a different social provider than the one already linked.

3. Compare the exact email spelling. Look for differences like:

name@company.com
name+work@gmail.com
Name@company.com
name@googlemail.com
name@gmail.com

If the two accounts differ only by alias, casing, or equivalent consumer-mail variations, this is probably your problem. Jump to Fixes → The app allows duplicate accounts when emails differ by alias/casing.

1. Rule out the wrong browser/social session. Start a private/incognito window, go to the app login page, click the social sign-in button, and carefully choose the correct social account in the provider popup. If using the correct social account logs you into the original account, this was your problem. Jump to Fixes → You signed into the wrong browser profile or wrong social account.

2. If both accounts already contain data, stop and contact support before changing anything. If each account has purchases, team memberships, or user-generated content, merging may affect ownership or audit history (a record of who did what). Jump to the matching fix below, but follow the support/escalation note first.

Fixes

Social provider returned a different email than your original account

1. Sign out of the unexpected account.
2. Sign in with the method that reaches your original account.
3. Go to Settings → Security → Connected accounts.
4. Click Link Google, Link Apple, or Link Microsoft from inside the original account.
5. Complete the social provider prompt using the account you actually want linked.
6. If the app does not offer self-service linking, contact support with both email addresses and ask for an account merge or provider relink.

Send support a note like this:

I have two accounts that belong to me.
Original account email: jane@company.com
New account email from social sign-in: jane.doe@gmail.com
Please merge or relink the social provider to the original account.

⚠️ If both accounts contain data, do not delete either account before support confirms which one will be kept. Deleting the wrong one can remove projects, invoices, or team access.

Verify it worked: sign out, click the same social sign-in button again, and confirm you land in the account with your original data.

You used a different social provider than the one already linked

1. Sign in to the original account.
2. Open Settings → Security / Connected accounts.
3. Check which provider is already linked.
4. Use that same button on the login page next time.
5. If you want multiple options, link the second provider from inside the original account.

Example target state:

Linked sign-in methods:
- Email + Password
- Google
- Microsoft

If the app only allows support-assisted linking, send support the provider names and the email shown by each provider.

Verify it worked: after signing out, both approved sign-in methods should open the same account ID/profile.

Apple "Hide My Email" created a relay address

1. Sign in to the account that has your real data.
2. Go to Settings → Security → Connected accounts and link Sign in with Apple from there if available.
3. During Apple sign-in, choose Share My Email if you want the app to receive your real address instead of a relay.
4. If the second account already exists with a relay address, ask support to merge:

Original account: jane@company.com
Apple relay account: 8f3c1a2b4d@privaterelay.appleid.com
Please merge these and keep the original account as primary.

If you are not sure what Apple sent, check the email shown on the account profile after signing in with Apple.

Verify it worked: signing in with Apple should now open the same account that your email/password login opens.

Your original account was created with email/password and the social login was never linked

1. Sign in with Email + Password.
2. Go to Settings → Security → Connected accounts.
3. Click Link next to the social provider you want to use.
4. Finish the provider prompt.
5. Sign out and test the social sign-in button.

If there is no Connected accounts page, ask support to attach the provider to your existing account instead of leaving the new account separate.

Verify it worked: the original account should list the provider as linked, and the social button should return you to that same account.

The app allows duplicate accounts when emails differ by alias/casing

1. Compare the two addresses exactly.
2. If they are really the same mailbox in practice, contact support and ask for normalization (treating equivalent forms as one identity) or a merge.
3. Include both forms in your message:

Account A: name@gmail.com
Account B: name+work@gmail.com
These reach the same mailbox. Please merge and keep Account A.

1. Until support confirms the merge, always use the exact same login method and exact same email spelling.

Verify it worked: after the merge or relink, the alias and the base address should no longer create separate accounts.

You signed into the wrong browser profile or wrong social account

1. Open a private/incognito window.
2. Go to the app login page.
3. Click the social sign-in button.
4. In the provider account chooser, select the correct account explicitly.
5. If needed, first sign out of the wrong Google/Microsoft/Apple account in that browser.

If you share a computer or use multiple browser profiles, label the right browser profile and keep work/personal identities separate.

Verify it worked: repeating the login in a clean private window consistently opens the expected account.

Prevention

• Link sign-in methods before you need them. After creating an account, open Settings → Security / Connected accounts and link your backup method now, not during an outage or device change.
• Standardize on one email form. Use the same address everywhere, without switching between aliases like:

name@gmail.com
name+work@gmail.com

• Document the primary login method in your team onboarding notes. Example:

Primary login for this workspace: Microsoft SSO
Backup login: Email + Password on the same account
Do not create a new account with Google

• If you are an app owner, add a post-login warning for suspected duplicates. For example, if a new social login returns an email that resembles an existing user, show a confirmation instead of silently creating a new account.

{
  "event": "social_login_no_exact_match",
  "action": "show_possible_existing_account_prompt"
}

• If you are an app owner, log identity-linking events. Keep an audit trail for support cases:

{
  "user_id": "12345",
  "event": "provider_linked",
  "provider": "google",
  "provider_email": "jane.doe@gmail.com"
}

• Test duplicate-account edge cases in QA. Before releasing auth changes, verify these paths: email/password first, then Google; Apple with Hide My Email; Microsoft on a different browser profile.

If you are still stuck, send support three things: the email on the old account, the email on the new account, and the exact sign-in button you clicked. That usually gives enough information to merge or relink the accounts without guesswork.
