Masked Text in eSignature Forms: Protect Sensitive Data in Multi‑Signer Workflows

TL;DR: BoldSign masked text fields help protect sensitive data in multi‑signer workflows by hiding values from other recipients after entry, so teams can securely collect information like IDs or bank details without slowing down approvals.

When documents pass through multiple signers, sensitive information can be seen by people who do not need access to it. Masked text in eSignature forms helps prevent unnecessary exposure by obscuring sensitive values after they are entered. With masked text fields in BoldSign, teams can collect sensitive information such as ID numbers, bank details, or personal contact data, while keeping the workflow moving.

This approach is especially useful in HR, finance, compliance, and operations workflows, where one person provides sensitive information and others only need to review or approve the document.

Why masked text fields matter

In multi-signer workflows, visibility is often broader than necessary. Without controls, personal or financial data can appear throughout the signing process, even when only one person needs to provide it.

That creates avoidable risk:

• Human impact: Employees, candidates, customers, and vendors lose trust when personal data is visible to people who do not need it.
• Business impact: Oversharing increases the risk of internal mishandling, screenshots, forwarding, or improper retention.
• Operational impact: Teams may move steps offline to protect data, slowing turnaround and increasing manual work.

Masked text fields provide a middle ground. They let teams collect required information while reducing who can view it after it’s entered.

Core concepts behind effective masking

• Masked text works best as part of thoughtful document design, not as a single setting applied everywhere.
• Masked text: A textbox value is hidden or obscured after entry so other viewers cannot read the original content.
• Data minimization: Only collecting and exposing information required to complete the process.
• Role-based field assignment: Assigning fields to specific recipients so only the appropriate signer enters the data.

When combined, these practices reduce exposure without making documents harder to complete.

How to decide what to mask

Not every field should be masked. The goal is protection without sacrificing clarity.

A field is typically a good candidate for masking when:

• It contains personally identifiable or financial information
• Later signers do not need to see the exact value
• Exposure would create risk if copied or shared
• The value supports verification or records, not decision‑making

Common fields to mask include:

• Government‑issued ID numbers
• Tax identifiers
• Bank account or payment information
• Employee or internal IDs
• Personal phone numbers or home addresses (when appropriate)

Fields such as names, job titles, or non‑sensitive operational details are usually better left visible to provide approval context.

How to mask sensitive information in BoldSign text fields

You can apply masking when preparing a document, template, or bulk link in BoldSign:

• Create your document and set up recipients and signing order.
• Go to the prepare page.
• Drag and drop a Textbox field onto the document.
• Assign the field to the signer who must provide the sensitive information.
• In Textbox Settings, enable Mask value.

Once enabled, the signer assigned to the textbox can see the value while entering it. Other recipients see a masked version after the field is completed, depending on document settings and permissions.

How masked values appear during signing

Masked fields protect privacy without blocking progress.

• The assigned signer can view the text they enter while signing.
• Other signers see only masked characters.
• The document remains readable and approvable without revealing high‑risk data.

This is especially useful in documents like NDAs, onboarding forms, or vendor agreements, where only one party needs to supply sensitive identifiers.

Visibility rules for masked text fields

In BoldSign, visibility follows a consistent model:

• Assigned signer: Sees the full value during entry
• Other signers: Never see the unmasked value
• CC recipients: Never see the unmasked value
• Sender: Can access the value after sending

This limits exposure while preserving sender access for operational needs.

Sender access to masked values

After sending a document, the sender can access masked values in two ways:

• View Document: Select the eye icon to reveal masked fields.
• Export Form Data: Download entered values as a CSV from the Document Overview page.

This supports workflows where data must be collected discreetly during signing but retained afterward.

When not to use masked text

Masked fields are not suitable for every situation.

Avoid masking when:

• Multiple signers must verify the exact value
• The document serves as a shared reference
• Later approvers must confirm accuracy, not just completion

In these cases, redesign the workflow, split the document, adjust the signing order, or add a controlled verification step instead of relying on masking.

Best practices for scaling safely

• Standardize templates so masking is applied consistently.
• Limit free‑text fields where sensitive data can leak.
• Maintain a simple internal list of fields considered sensitive.
• Test workflows from each signer’s perspective.
• Align document storage and export permissions with masking intent.

Common mistakes to avoid

• Masking everything by default: Over‑masking reduces clarity. Protect only genuinely sensitive fields.
• Incorrect field assignment: Always assign masked fields to the correct signer to avoid confusion or exposure.
• Using masking instead of fixing workflows: If multiple people must review a value, redesign the process instead.
• Skipping multi‑recipient testing: Test visibility for each signer, not just from the sender’s view.

Conclusion

Masked text in eSignature forms helps teams handle sensitive data more responsibly in multi-signer workflows. When applied selectively and combined with solid workflow design, it reduces unnecessary exposure without adding friction.

To get started, try using masked text in a test document and review visibility from each signer’s perspective.
