Switching from email to social loginUpdated 2 months ago

Why Switch to Social Login?

If you currently log in with email and password, you can add Apple Sign-In or Google Sign-In to your account for these benefits:

  • Faster login: One tap instead of typing credentials
  • No password to remember: Use your existing Apple ID or Google account
  • More secure: Leverage Apple/Google's security infrastructure and two-factor authentication
  • Works everywhere: Available on iOS, Android, and Web

Important: You don't have to choose one or the other - you can keep your email/password AND add social login as an alternative. Use whichever is most convenient at the time.

How to Add Social Login to Your Account

Currently, adding Apple Sign-In or Google Sign-In to an existing email account requires contacting support. Here's the process:

Step-by-Step Process

  1. Contact CENTR support at [email protected]
  2. Subject line: "Link Apple Sign-In to My Account" or "Link Google Sign-In to My Account"
  3. Include in your message:
    • Your current CENTR email address (the one you use for login)
    • Which social login you want to add (Apple, Google, or both)
    • Your Apple ID email or Gmail address
    • Confirmation that you want to link these accounts
  4. Support will verify:
    • That you own both the CENTR account and the social account
    • Your account details match
  5. Support links the accounts (usually completed within 24 hours)
  6. You receive confirmation that linking is complete
  7. Try logging in using "Sign in with Apple" or "Continue with Google"

Example Email to Support

Here's what to write:

"Hi, I currently log in to CENTR with email/password using [email protected]. I'd like to add Apple Sign-In to my account so I can use either login method. My Apple ID email is [email protected]. Please link these accounts. Thanks!"

What Happens After Linking

You'll Have Multiple Login Options

After linking is complete, you can log in using:

  • Option 1: Your email and password (still works)
  • Option 2: "Sign in with Apple" button
  • Option 3: "Continue with Google" button (if you linked Google too)

All three methods log you into the same CENTR account with the same workout history, subscription, and data.

Choose Whichever Is Most Convenient

  • Use social login on your phone (faster with Face ID/Touch ID)
  • Use email/password on shared devices where you're not signed into Apple/Google
  • Use different methods on different devices if you prefer

Platform Differences

Linking Apple Sign-In

Best for:

  • iPhone/iPad users
  • Users who value privacy (Apple's "Hide My Email" option)
  • Users with Face ID or Touch ID for instant login

Available on: iOS, Android, and Web

Note: If you enable "Hide My Email" when linking, be aware this creates an Apple Private Relay email. We recommend using "Share My Email" instead when linking to an existing account to avoid confusion.

Linking Google Sign-In

Best for:

  • Gmail users
  • Android device users
  • Users already signed into Google Chrome

Available on: iOS, Android, and Web

Tip: Make sure to use the same Gmail address you want associated with CENTR. If you have multiple Gmail accounts, choose carefully.

Important Considerations

Linking is permanent. Once you link Apple Sign-In or Google Sign-In to your account, you cannot unlink it. However, this doesn't cause any problems - you simply have the option to use social login, and you can still use email/password if you prefer.

What If You Used Social Login to Create Your Account?

If you originally created your CENTR account using "Sign in with Apple" or "Continue with Google," and now want to ADD email/password login as a backup:

  1. Contact support at [email protected]
  2. Request to add email/password login to your social login account
  3. Support will help you set up a password
  4. You'll then be able to use either method

Linking Both Apple AND Google

Yes, you can link both Apple Sign-In and Google Sign-In to your account:

  • You'll have three login options: email/password, Apple, and Google
  • All three authenticate to the same CENTR account
  • Use whichever is most convenient

Just contact support and specify you want to link both social login options.

Troubleshooting

Social Login Creates a New Account Instead of Linking

If you tap "Sign in with Apple" or "Continue with Google" before support links your accounts, it might create a new separate account. If this happens:

  1. Contact support immediately
  2. Provide both email addresses (your original email and the new social login email)
  3. Support will merge the accounts, preserving your subscription and workout data

Wrong Social Account Was Linked

If support linked the wrong Apple ID or Gmail address:

  • Contact support again with the correct email addresses
  • They can update the link to the correct social account

Can't Log In with Social Login After Linking

  • Make sure support confirmed the linking is complete
  • Wait 24 hours after support confirms (sometimes takes time to propagate)
  • Try logging out completely and back in
  • Clear app cache or reinstall the app
  • Try on a different platform (app vs web)

Security Considerations

Is Social Login Secure?

Yes, social login is considered very secure:

  • Leverages Apple/Google's advanced security infrastructure
  • Benefits from their two-factor authentication
  • No need to create and store another password
  • Reduces risk of password reuse across sites

Protecting Your Accounts

To keep your CENTR account secure when using social login:

  • Enable two-factor authentication on your Apple ID or Google account
  • Use a strong password for your Apple ID or Google account
  • Keep email/password login as a backup in case you lose access to Apple ID or Google
  • Don't share your Apple ID or Google credentials

Common Questions

Will my workout data and subscription transfer?

Yes! Linking social login to your existing account doesn't change your data - it just adds a new way to authenticate. All your workout history, subscription, and settings remain exactly the same.

Do I have to use social login after linking it?

No, you can continue using email/password if you prefer. Social login is just an additional option.

Yes, but personal Gmail is recommended because you'll always have access to it. If you lose access to your work/school Google account, you'll still have email/password as a backup.

What if I change my Apple ID or Gmail address later?

Contact CENTR support to update the linked email. They'll verify your identity and update the linked social account.

How long does linking take?

Support typically completes the linking within 24 hours of receiving your request. You'll receive confirmation when it's done.
