Account protection
Mandatory two-factor authentication adds a second verification step to every sender account.
Document signing security
Security for Online Document Signing
Bond4Docs combines account protection, encrypted sensitive values, secure recipient links, event logging, expiration controls, and tamper-evident completion information to protect common electronic-signature workflows.
Free · No credit card · No signing limits
Protected workflow data
Sensitive field values and signature data support AES-256-GCM encryption at rest.
Evidence after completion
Audit activity and SHA-256-based certificate records help reveal later changes.
Layered security from account to recipient
A signing workflow crosses several trust boundaries: the sender account, the stored document, the email invitation, the recipient session, and the completed record. Bond4Docs applies controls at each stage rather than relying on one login screen.
- Two-factor authentication for account access
- Cryptographically random recipient tokens
- Automatic link and document expiration options
- AES-256-GCM encryption support for sensitive stored values
- Timestamped event and IP activity records
- SHA-256-based tamper-evident completion information
What a completion certificate tells you
Bond4Docs completion records use hashes of the document, signature information, and captured audit activity. A public certificate identifier can be used to check the stored certificate record. Hash comparison is designed to make later modification detectable; it is not the same as notarization or government identity verification.
Choose the right signing method for the risk
Routine business agreements and acknowledgements may use standard electronic-signature workflows, while wills, court documents, notarized instruments, regulated transactions, or high-value agreements may require additional controls. Consult qualified counsel about the document and jurisdiction when the consequences are significant.

Frequently asked questions
Does Bond4Docs use encryption?
Bond4Docs supports AES-256-GCM encryption at rest for sensitive values including document titles, signer-entered field values, and signature data when document encryption is configured.
Does Bond4Docs require two-factor authentication?
Yes. Account holders must use a second factor through email verification or a compatible authenticator app.
Are signing links public?
Each request uses a cryptographically random token. Signing URLs are excluded from the public sitemap and marked to stay out of search indexes.
Is Bond4Docs a notary or identity-verification service?
No. Bond4Docs provides an electronic-signature workflow, not notarization, knowledge-based authentication, or government ID verification.
