# `OAUTH_EMAIL_IN_USE` This email already has a Checkslip account

Source: https://checkslip.com/en/problems/oauth-email-in-use

- **HTTP status**: `409`
- **Credit**: No credit taken

## Meaning

Sign in with that account's password, then connect the provider account in settings. We never connect it on our own, even when the email matches.

## Fix

Sign in with this email (use "Forgot password" if needed), then connect it in settings.
