Why there's no account
Accounts exist so a service can store your documents and signatures on its servers. OpenSigner doesn't store them, so it doesn't need to know who you are. Your preferences (theme, your signer name, your last signature) are kept in your own browser's local storage, and you can clear them at any time.
What you get in the signed file
- Your signature, initials, date and text placed exactly where you put them, on any page.
- A completion certificate page with the document name and size, the signer name and role you entered, the signing time in local time and UTC, your browser environment, and SHA-256 hashes before and after signing.
- A QR code linking to the verifier, so the recipient can check the file is unchanged.
What a simple electronic signature is (and isn't)
OpenSigner creates a simple electronic signature: a visible signature mark plus tamper evidence. It does not check your identity, and it is not a certificate-based digital signature (such as one backed by a certificate from a licensed certification authority, or a qualified electronic signature). Many everyday agreements accept simple e-signatures, but some documents legally require a stronger type. If you're unsure, check with the party you're signing for or a lawyer, and see our country-by-country guide to e-signature laws.
