Sign In with Google

The Account Everyone Already Has

1.8 billion people use Gmail. 90% of Fortune 500 companies run on Google Workspace. When someone receives a shared document link, the last thing they want is to create yet another account with yet another password. Google sign-in removes that barrier entirely.

PaperLink supports Sign in with Google as its primary authentication method - alongside LinkedIn and Telegram.

How It Works

Click "Continue with Google" on the sign-in page. Google's familiar account picker appears - select your account, and you're in PaperLink. If you're already signed into Google in your browser, the entire flow takes one click.

No registration form. No email verification step. No password to create or forget. Google confirms your identity through OAuth 2.0 and shares your name, email, and profile photo with PaperLink. Your Google password never touches our servers.

What's Included

Feature	How It Works
Sign in	"Continue with Google" button on the login page
Connected Accounts	Link or unlink Google in Profile Settings at any time
Multiple providers	Use Google and LinkedIn simultaneously - both point to the same account
Account safety	Cannot disconnect your last remaining login method

Already signed up with LinkedIn or Telegram? Go to Profile Settings → Connected Accounts, click Connect next to Google, and authorize. Your existing account gains Google as an additional login method.

Why Google Is the Default

Three facts shaped this decision.

Universal reach. Google accounts span every industry, every country, and every device. Whether your document recipient is a lawyer in Singapore, a contractor in Berlin, or a compliance officer in Sao Paulo - they have a Google account. No other identity provider comes close to this coverage.

Zero-friction onboarding. Adding Google sign-in to SaaS platforms increases signup conversion by 20% on average. In A/B tests, one-click Google authentication has shown conversion lifts exceeding 100% compared to email/password forms. For PaperLink, this matters at the moment a shared document recipient decides whether to create an account and respond - every second of friction is a lost opportunity.

Enterprise-grade security. Google's OAuth 2.0 implementation includes automatic token refresh, phishing-resistant authentication, and integration with Google Workspace admin policies. Organizations that enforce two-factor authentication on Google accounts get that protection extended to PaperLink automatically - without any additional configuration on our side.

Three Ways to Sign In

PaperLink offers three authentication options:

• Google - universal, works for everyone with a Google account
• LinkedIn - professional identity, common in B2B and enterprise contexts
• Telegram - dominant in APAC, CIS, and mobile-first markets

Each option uses industry-standard protocols (OAuth 2.0 / OpenID Connect). Your credentials stay with the identity provider. PaperLink receives only what you authorize: name, email (or phone for Telegram), and profile photo.
