Social Login Providers
You can register and log in to EU CAPTCHA using an account from a supported identity provider instead of (or in addition to) a password.
Supported providers
| Provider | Notes |
|---|---|
| Sign in with your Google account | |
| GitHub | Sign in with your GitHub account |
| Apple | Sign in with Apple ID |
| Okta | For enterprise SSO via Okta |
| SAML | Generic SAML 2.0 SSO integration |
Passkeys (WebAuthn) are also available as a login method alongside social providers. See Passkeys.
Button order
Button order is optimised for the detected device. The passkey button only appears on the login page — it is not shown on the registration page.
Login page
| Device | Button order |
|---|---|
| Apple (macOS, iPhone, iPad) | Apple → Passkey → Google → GitHub |
| Android | Google → GitHub → Passkey (Apple Sign In is omitted as it is unreliable on Android) |
| All other devices (Windows, Linux, …) | Passkey → Google → GitHub → Apple |
Registration page
| Device | Button order |
|---|---|
| Apple (macOS, iPhone, iPad) | Apple → Google → GitHub |
| Android | Google → GitHub (Apple Sign In is omitted as it is unreliable on Android) |
| All other devices (Windows, Linux, …) | Google → GitHub → Apple |
Using a social login
Registration
- On the registration page, click the button for your preferred provider (e.g. Sign up with Google).
- You are redirected to the provider's authentication page.
- Authorise EU CAPTCHA to access your basic profile (name and email).
- You are redirected back and your account is created automatically.
No separate email verification step is required when using a social provider, as the provider has already verified your email.
Logging in
On the login page, click the button for your social provider. After authenticating with the provider you are logged in to EU CAPTCHA immediately.
Okta and SAML (enterprise)
Okta and SAML support are intended for organisations that manage employee authentication centrally via an Identity Provider (IdP). Contact Myra Security support to configure SAML SSO for your organisation.
Multiple login methods
You can link multiple login methods to one account (e.g. password + Google + passkey). All methods log you in to the same account.
If you registered with a social provider and later want to add a password, contact support.
