Best Digital Signature Software 2025 for SignNow
Award-winning eSignature solution
What this software does
Best digital signature software 2025 helps businesses prepare documents, send them to the right signers, capture consent electronically, and preserve a record of the transaction. In the U.S., the legal value comes from ESIGN and UETA, which recognize electronic signatures when the signer intends to sign and the record can be tied back to that person. SignNow adds templates, mobile signing, audit trails, and compliance controls for everyday and regulated workflows.
Legal value and enforceability
Best digital signature software 2025 supports U.S. transactions by capturing intent, attribution, and a tamper-evident record. Under ESIGN and UETA, that evidence can make a signed record admissible and enforceable, while organizations still need appropriate consent, retention, and identity controls.

Platform and device requirements
SignNow works in current Chrome, Firefox, Safari, and Edge browsers, and it also supports mobile app access on iOS and Android. A secure connection with TLS 1.2 or later is expected for signing sessions and account access.
Browser support Chrome, Firefox, Safari, and Edge on current versions. Operating systems Windows 11, macOS, iOS, and Android devices. Connection and access TLS 1.2 or newer, plus mobile apps.
For managed deployments, browser updates, device controls, and mobile app policies matter more than special hardware. Organizations that use SSO, API access, or regulated record retention should pair supported browsers with approved devices, enforced authentication, and consistent archival controls.
User roles and permissions
Admins in SignNow can manage team access, shared templates, and delegated sending so department members use approved workflows without changing document controls. This is useful when legal, operations, and sales need the same process but different permissions for sending, editing, or approval routing. Workspace owners can assign roles for template creation, signer routing, and record access, which helps reduce accidental changes to final forms. Shared libraries and delegated sending support centralized governance while still letting regional teams send recurring documents from preapproved templates with less manual effort.
FAQ and troubleshooting
These answers focus on specific workflow, security, and compliance issues that arise when teams use electronic signatures in business settings.
If a signer says the document was changed after signing, check the audit trail, document hash, and completion certificate. SignNow records event history and timestamps, which help show whether the file remained intact after signature capture.
If HIPAA documents need to be retained, keep the signed record for 6 years under 45 CFR 164.530(j)(2). SignNow can store completed files, but your retention policy should also cover exports and backups.
If a signer cannot open a request in Safari or Chrome, confirm the browser is current and that TLS 1.2 or later is enabled. SignNow supports modern browsers, but outdated settings can block secure access.
If a team member should not edit templates, review role permissions and delegated sending settings. SignNow account administration can restrict who creates templates, sends requests, or accesses completed records.
If a healthcare workflow needs a BAA, verify that your SignNow plan and contract terms include it before moving PHI. HIPAA compliance depends on vendor agreements, access controls, and audit logging, not signatures alone.
If records need stronger authentication, use SMS OTP, ID verification, or other higher-assurance methods instead of basic email delivery. The right method depends on the document risk, the industry, and the evidence you need later.
