What You Need to Know

✅ Great News!

WeightSyncr fully supports Garmin Connect accounts with 2FA enabled. The setup process is identical to non-2FA accounts, with just one additional verification step.

Two-factor authentication (2FA) adds an extra security layer to your Garmin Connect account. Here's what you need:

Your Garmin Connect account
Access to the verification method associated with that Garmin account
WeightSyncr app installed on your iPhone

Connection Process

Connecting your 2FA-enabled Garmin account is straightforward:

Open WeightSyncr and go to the Settings tab
Tap "Connect Garmin Account"
Follow the prompts to authenticate with Garmin
Complete verification if Garmin requests a code
Wait for the connection to complete
Verify you see "Connected" status in Settings

Security Note: Only enter a verification code while completing the Garmin authentication flow, and never share a code with another person.

That's it! Your 2FA-enabled account is now connected and you can start syncing weight data.

Troubleshooting 2FA

2FA Code Not Working

Use the newest code: Verification codes expire, so request another if needed
Check the configured method: Look wherever Garmin normally sends your account verification code
Check filtered messages: If Garmin sent an email, inspect junk or spam folders
Retry once: Start a fresh authentication attempt rather than reusing an older code

"Authentication Failed" Error

Test Garmin sign-in: Sign in to Garmin Connect directly to confirm the account is available
Check the verification code: Make sure it belongs to the current connection attempt
Try again: Sometimes temporary server issues cause authentication failures

Stuck During Authentication

Close and retry: Force close WeightSyncr and start the connection process again
Check network: Ensure you have a stable internet connection
Disable VPN: Some VPNs interfere with authentication processes

Periodic Reconnection

For security reasons, 2FA-enabled accounts may require periodic re-authentication:

📅 Reconnection Prompt

Garmin may occasionally require you to authenticate again before syncing can continue.

When this happens: WeightSyncr will show "Disconnected" in Settings, and syncs will fail until you reconnect.

How to Reconnect

If you see a "Disconnected" status after syncing previously worked:

Go to WeightSyncr Settings
Tap "Connect Garmin Account" (no need to disconnect first)
Authenticate with Garmin and complete verification if requested
Your sync history and settings remain intact

Reconnecting does not change the weight entries already shown in WeightSyncr.

Security Benefits

Using 2FA adds another verification step when Garmin needs to confirm a connection:

Account Protection

Two-factor authentication asks for an additional verification step when Garmin detects a new sign-in or connection.

Data Privacy

Garmin authentication and 2FA help protect access to your connected account.

🏆 Best Practice

We recommend enabling 2FA on your Garmin Connect account for maximum security. WeightSyncr works seamlessly with 2FA and adds no complexity to your daily use.
