# Does Google Calendar Sync Work with Two-Factor Authentication (2FA)?

Yes — Google Calendar sync works perfectly fine with two-factor authentication enabled on your Google account.

Yes — Google Calendar sync works perfectly fine with two-factor authentication enabled on your Google account. You do not need to disable 2FA to connect your calendar.

## How the connection works [#how-the-connection-works]

Chatfuel connects to Google Calendar using OAuth, Google's standard secure sign-in method. When you link your Google account, you sign in through Google's own login page and grant Chatfuel permission to access your calendar. This process fully supports 2FA — you'll simply complete your usual second verification step (authenticator app, SMS code, or security key) during sign-in, just like logging into any other service.

Once connected, the sync stays active. You won't need to re-authenticate every time.

## What you need to do [#what-you-need-to-do]

1. Open [Google Calendar settings](https://chatfuel.com/docs/calendar/how-to-connect-google-calendar) in Chatfuel.
2. Generate a connection link for the specialist and open it.
3. Sign in to your Google account — complete your 2FA prompt as usual.
4. Grant Chatfuel permission to read your calendar.

That's it. Your Google Calendar events will sync into your Chatfuel [Calendar](https://chatfuel.com/docs/calendar/calendar). The sync is one-way: bookings created in Chatfuel do not appear in Google Calendar.

## FAQ [#faq]

**Will I need to reconnect if I change my 2FA method?**

No. The connection uses a token that persists independently of your 2FA settings. Changing from SMS to an authenticator app (or vice versa) won't break the sync.

**What if the sync stops working?**

If your Google session expires or you revoke access, you may need to reconnect. Just repeat the steps above — 2FA will work the same way during re-authentication.
