How to Switch Between Google and Apple Sign-In

Last updated: August 20, 2026

Overview

Mezzi signs you in with Apple or Google only — there's no password to change and no in-app setting to switch which one your account uses. Changing the sign-in identity on an existing account is a manual change our team makes for you. Email help@mezzi.com with the identity you use now and the one you want to move to, and we'll move the account rather than making you start over.

🧭 How to Request the Switch

  1. Email help@mezzi.com from an address you can be reached at.

  2. Tell us the email address your Mezzi account uses today — the one you signed up with.

  3. Tell us the email address you want to sign in with going forward, and whether that's an Apple or a Google identity.

  4. Wait for confirmation before signing in again. Once we've made the change, sign out and sign back in with the new provider.

There is no self-serve version of this today. If you're looking for a "change email" or "change sign-in method" option in settings, it isn't there — you haven't missed it.

💡 Why This Matters

Signing in with the wrong provider looks like data loss, but isn't. If your Apple ID and your Google account use different email addresses, signing in with the other one creates or opens a separate Mezzi account — empty, with none of your connections. Your original account and everything in it is still intact under the original identity. Sign out, sign back in with the provider you originally used, and it's all there.

Apple's Hide My Email makes this easier to hit. If you signed up through Apple and chose to hide your email, your Mezzi account is tied to a relay address rather than your everyday one. That's the identity to tell us about when you write in.

Ask before you delete. If you've ended up with a second, empty account and want it gone, tell us — deleting the wrong one is permanent. See How to Delete Your Mezzi Account and Data.

Important Notes

We can move the sign-in identity on an existing account, which keeps your connected accounts, holdings and history in place. We can't merge two accounts that both already have data — if you've built up connections under both identities, tell us and we'll work out the cleanest path with you.

Common Questions

  • Can I set a password instead of using Apple or Google? No. Mezzi uses Apple and Google single sign-on only. There's no Mezzi password to set, which also means there's no Mezzi password to be stolen.

  • I signed in and my accounts are gone. What happened? You've almost certainly signed in with the other provider, which opened a different account. Sign out and sign back in with the identity you originally used — your data is untouched.

  • How long does the switch take? It's handled by our team rather than automatically, so it isn't instant. Email us and we'll confirm when it's done.

  • Will I have to reconnect my accounts afterward? No. Moving the sign-in identity on an existing account leaves your connections and holdings in place.
