Which social login providers should we support?

For B2C apps, we recommend Google and Apple at minimum (Apple is required for iOS apps with social login). For developer tools, add GitHub. For B2B, add LinkedIn and Microsoft. We can add any OAuth 2.0 provider.

How do you handle users who sign up with both email and social?

We implement account linking that detects matching email addresses and prompts users to link accounts. This prevents duplicate accounts and allows users to sign in with any linked method.

Is social login secure?

Yes. Social login uses OAuth 2.0 with PKCE, which is more secure than email/password. Your application never handles passwords, and users benefit from their social provider's security features including 2FA.

Reduce Sign-Up Friction with Social Login

Bookuvai integrates Google, GitHub, Apple, and other social login providers with account linking, profile enrichment, and seamless onboarding flows.

Feature: Social Login

Social login lets users sign up and log in with their existing Google, GitHub, Apple, LinkedIn, or other social accounts, reducing registration friction by up to 50%. A well-implemented social login system handles account linking (merging social and email accounts), profile data enrichment, token management, and provider-specific quirks across platforms.

Benefits

Reduced Sign-Up Friction: Social login reduces registration time from 2 minutes to 2 seconds, increasing sign-up conversion rates by 20-50% compared to email/password forms.
Verified Email Addresses: Social providers verify email addresses, eliminating the need for email verification flows and reducing fake account creation.
Profile Data Enrichment: Automatically populate user profiles with name, avatar, and other data from social providers, reducing onboarding form fields.
Higher Security: Users rely on their social provider's security (including their 2FA), and your application never handles or stores passwords.

How It Works

Provider Selection and Setup: We configure OAuth applications with each social provider, setting up redirect URIs, scopes, and consent screens for your brand.
OAuth Flow Implementation: We build the OAuth 2.0 authorization code flow with PKCE, state parameter validation, and secure token exchange for each provider.
Account Linking Logic: We implement intelligent account linking that merges social accounts with existing email accounts, handling edge cases and user consent.
Profile Sync and Session Management: We sync profile data from social providers, set up session management, and handle token refresh for continuous access.

Technology Options
