"Token Missing" Error When Signing in with Google or Microsoft

Why this happens

When you try to sign in using Google or Microsoft, Myphoner redirects you between secure subdomains (like from login.myphoner.com to your team’s workspace at yourcompany.myphoner.com). Sometimes, browsers block or clear cookies during that process, which causes the login to fail with a "Token missing" or "Could not connect!" error.

This is especially common in Safari, Firefox, or when using strict privacy or tracking protection settings. In some cases, if your account has been canceled, you may also experience authentication failures.

🧩 How to fix it

Try one of these strategies — whichever is easiest for you:

✅ Option 1: Use a different browser or incognito/private mode

Browsers like Chrome and Edge tend to be more permissive with cookies in cross-subdomain flows. Incognito mode can also help by starting with a clean slate.

✅ Option 2: Adjust your browser settings

Some browsers block essential cookies by default. You can fix this by allowing cookies and disabling strict tracking protection.

Here’s how:

  • Safari (Mac & iPhone/iPad)
    Go to Settings > Safari and turn off:
    ​Prevent Cross-Site Tracking

  • Firefox
    Go to Preferences > Privacy & Security, and set Enhanced Tracking Protection to Standard

  • Chrome & Edge
    These browsers typically work out of the box. If you have extensions that block cookies or tracking, try disabling them or whitelisting Myphoner.

✅ Option 3: Use email/password instead of third-party login

If you continue to experience issues with Google or Microsoft login, try signing in with your email address and password instead. This bypasses the cross-domain authentication process that can cause cookie-related problems. Contact support to disconnect your SSO and set a password.

✅ Option 4: Verify your account status

If you've tried the above solutions and still can't log in, check that your account hasn't been canceled or deactivated. Users with canceled accounts will not be able to access the platform.
