Proton VPN Login Not Working
Workaround available Windows, macOS, Linux, iOS, Android Updated November 13, 2026Based on 2 user reportsHow we research
Quick answer
Sign-in usually fails because Proton is blocked on your network, human verification won't load, the 2FA code is rejected because of clock drift, or the app is outdated. Turn on alternative routing, switch verification method, fix your clock and update the app.
Most likely fix: Enable alternative routing
How to fix it
Try these in order — the most common fix is first.
1. Enable alternative routing
- In the app settings, make sure Alternative routing is on
- Try signing in again; the app will reach Proton through third-party networks if Proton is blocked

- If the CAPTCHA fails, choose email or SMS verification instead
- If no verification options appear, contact Proton support
Did this fix it?3. Fix 2FA code errors
- Set your phone clock to automatic so it is within two minutes of the real time
- If you lost your authenticator, sign in with a recovery code
Did this fix it?4. Update or reinstall the app
- If you can sign in at account.protonvpn.com but not in the app, update the app
- If that fails, uninstall, download the latest version and sign in again
Did this fix it?5. Use OpenVPN credentials for manual setups
- Routers and third-party clients need your separate OpenVPN / IKEv2 username and password from your Proton VPN account, not your Proton login

Symptoms
The app hangs on sign-in or human verification, says it can't reach Proton, or rejects your 2FA code.
Why it happens
- Proton's servers are blocked on your network or in your country
- CAPTCHA human verification fails or never loads
- Phone clock is off, so 2FA codes are rejected
- Outdated or broken app install
- Using Proton Account credentials in a manual OpenVPN config (it needs separate OpenVPN credentials)
