Sign In with LinkedIn

The Identity Your Contacts Already Know

Google verifies an email address. LinkedIn verifies a professional identity. When you share contracts, compliance documents, or invoices, both sides of the transaction need to know who they are dealing with. A Gmail address tells you nothing about the person behind it. A LinkedIn profile tells you their role, company, industry, and history.

PaperLink now supports Sign in with LinkedIn - alongside Google and Telegram.

How It Works

Click "Continue with LinkedIn" on the sign-in page. PaperLink redirects you to LinkedIn's authorization page, where you approve access to your name and email. LinkedIn confirms your identity through OpenID Connect - the same standard protocol used by Google - and redirects you back to PaperLink with your account ready.

No new password. No registration form. The professional identity you maintain on LinkedIn becomes your PaperLink login.

Why LinkedIn Matters for Document Sharing

Three reasons this is more than a convenience feature.

Professional trust. LinkedIn has 1.2 billion registered members, including 65 million decision-makers and 10 million C-level executives. When a recipient sees that a shared document came from someone who authenticated with their LinkedIn identity, it carries implicit credibility. The person is accountable - their professional reputation is attached.

B2B audience alignment. PaperLink serves legal professionals, construction executives, and compliance teams. These are industries where LinkedIn is the default professional network. The largest industry segment on LinkedIn is Professional Services with 23 million members - including the lawyers and consultants who share documents through PaperLink daily.

Reduced friction at the point of trust. Sharing a confidential document is a trust transaction. The recipient decides whether to open, read, and respond. Every second of friction - creating an account, verifying an email, setting a password - is a moment where that transaction can break down. LinkedIn login removes that friction for professionals who already live on the platform.

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 OpenID Connect, the industry standard for secure authentication. Your credentials stay with the identity provider. PaperLink receives only what you authorize: name, email (or phone for Telegram), and profile photo.
