Google is rolling out a new app that stores your digital signature on your device and across trusted cloud services. This initiative aims to streamline how you prove your identity online while reducing reliance on passwords.
The tool is designed to integrate tightly with Android, Chrome, and Google Workspace, giving you a consistent way to authenticate documents and transactions. Below is a quick overview of how the service is structured and what to expect.
| Platform | What is stored | Security model | User controls | Supported actions |
|---|---|---|---|---|
| Android | Cryptographic key pair tied to your identity | Hardware-backed keystore when available | App permissions, account removal, backup toggle | Sign documents, approve login, reset passwords |
| Chrome on desktop | Profile-bound digital signature credentials | Sync encryption with passphrase option | Manage devices, revoke sessions, export requests | Fill forms, sign PDFs, verify emails |
| Google Workspace | Verified organizational identity | Admin-managed policies and audit logs | Role-based access, compliance rules | Approve contracts, sign as org, delegate access |
| Third-party apps | stored via Google One APIs scoped OAuth token usage consent screens and revocation one-click login and document signing
How the Digital Signature Storage Works Under the Hood
When you opt into the new app, Google creates a cryptographic identity anchored in your device or Google account. Keys are either kept in a secure element or encrypted with a passphrase you control.
Each signature is tied to a policy that defines where it can be used and for how long. You can review and rotate keys, revoke specific sessions, and set expiration rules for shared documents.
Signing Documents and Approving Workflows
In day to day use, the app lets you sign contracts, proposals, and internal forms without leaving Chrome or Android. You receive clear prompts that show what you are approving and where the data will go.
Workflow integrations with Google Docs, Drive, and Workspace tools mean you can request a signature, track status, and receive notifications when actions are completed or declined.
Privacy, Compliance, and Data Handling
Google outlines strict privacy rules around your digital signature, including limited sharing with third party services and transparency logs you can audit. Data is retained only as long as required for legal, security, or business purposes.
Compliance frameworks such as GDPR, CCPA, and industry specific standards are mapped to specific features, helping organizations understand how controls align with their obligations.
Getting Started and Best Practices
- Enable two factor authentication before storing high privilege signing keys.
- Review connected apps and revoke outdated integrations regularly.
- Set sensible expiration periods for documents signed with time bound keys.
- Use device backed storage for daily signing and cloud backup only when necessary.
- Monitor audit logs for unusual activity and sign requests you did not initiate.
FAQ
Reader questions
Can I use this digital signature app without storing anything in my Google account?
You can limit storage to your device by disabling sync for identity data, though some features like cross device access and admin controls will require a Google account.
How does the app protect my private key if my phone is lost?
Remote sign out and key revocation through your Google account help prevent unauthorized use, and optional hardware backed storage adds an extra layer of protection.
Will organizations be able to audit who signed what and when?
Yes, Workspace admins can access detailed audit logs that record each signing event, associated documents, and the verification status of signers.
Can I export my digital signature or move it to another provider?
You can request export of public keys and associated metadata, though private key material is generally non exportable to maintain security.
