Google OAuth Login
Sign in to Wintro using your Google Workspace account.
Google OAuth login lets you sign in to Wintro with your existing Google Workspace or personal Google account. No password to remember, no separate setup required for most users.
Note: This is different from Google SSO (SAML), which a Wintro admin enables per email domain to enforce sign-in through your IdP. Google OAuth login is opt-in per user and works out of the box.
How It Works
- On the Wintro login page, expand View all login methods and click Continue with Google
- You’re redirected to Google’s account chooser
- Pick your Google account and grant Wintro consent on the permissions screen
- You’re back in Wintro, logged in
Permissions Requested
The Google OAuth flow is unified, so the consent screen lists all three scopes Wintro can use, even when you’re only signing in:
| Scope | Purpose |
|---|---|
https://www.googleapis.com/auth/userinfo.email | Identify your Wintro account |
https://www.googleapis.com/auth/userinfo.profile | Display your name in Wintro |
https://www.googleapis.com/auth/gmail.send | Send nudge emails on your behalf when you select Gmail as your email provider |
You can decline the gmail.send scope and still complete login — Wintro tracks which scopes were actually granted. If you later try to switch to Gmail as your email sender, Wintro will prompt you to reconnect and grant the missing permission.
Admin Approval Required (Sometimes)
Depending on your Google Workspace admin’s settings, you may see a “This app is blocked” or “Request access” message when you click Continue with Google. This means your admin has restricted which third-party apps users can authorise.
If You See This Message
- Contact your Google Workspace administrator
- Share the Wintro login page URL
- Ask them to allow Wintro under Admin console > Security > Access and data control > API controls > Manage third-party app access
For Google Workspace Admins: Allowing Wintro
- Sign in to admin.google.com as a super admin
- Go to Security > Access and data control > API controls
- Click Manage third-party app access > Add app > OAuth App Name or Client ID
- Search for Wintro
- Choose Trusted (or Limited with the three scopes listed above) and apply to your whole organisation or selected OUs
After approval, users can sign in immediately.
Troubleshooting
“This account doesn’t exist in Wintro” — Your Google account isn’t linked to a Wintro user. Ask your Wintro admin to add you to the team, then try again.
“App blocked” — Your Google Workspace admin has restricted third-party app access. See the section above.
Stuck on the consent screen — Try an incognito window. If your browser auto-selected the wrong Google account, signing out of all Google accounts and retrying usually fixes it.
