Choosing a password sharing tool: the ultimate checklist

The market for secure credential-sharing tools has grown significantly in recent years. From self-hosted open-source tools to SaaS products with enterprise features, the options range from free to expensive, simple to complex, generic to specialized.

Choosing the right tool for your organization requires evaluating it across multiple dimensions. This checklist covers them all — use it to compare tools and identify which best fits your requirements.

Section 1: Core security features

These are non-negotiable for any tool in this category.

• [ ] Credentials are deleted automatically after first retrieval
• [ ] Links expire after a configurable maximum period, even if not retrieved
• [ ] Data is encrypted in transit (HTTPS/TLS)
• [ ] Data is encrypted at rest on the server
• [ ] The tool does not store credentials longer than necessary
• [ ] The vendor cannot access credentials in plaintext (zero-knowledge preferred)
• [ ] There is no persistent unencrypted copy in any communication channel

Section 2: Data residency and compliance

Critical for EU-based organizations. Our overview of EU-hosted secure password sharing tools shows how the main options compare on this front.

• [ ] Servers are hosted within the EU (or your required jurisdiction)
• [ ] The vendor can provide a signed Data Processing Agreement (DPA)
• [ ] Data residency is contractually guaranteed, not just stated in marketing
• [ ] The vendor publishes a privacy policy that clearly describes data handling
• [ ] There is a process for Data Subject Access Requests if applicable
• [ ] The vendor has a published security policy or trust page
• [ ] The vendor will notify you of data breaches within GDPR-required timeframes

Section 3: Usability for senders

Your team needs to use this tool efficiently.

• [ ] Creating a credential link takes under 60 seconds
• [ ] Expiry time is configurable per link (not a fixed platform default)
• [ ] The interface is available in the languages your team uses
• [ ] No complex account setup is required to start using it
• [ ] Multiple credential fields can be included in a single link (e.g., username + password)
• [ ] The tool works on mobile as well as desktop
• [ ] There is a way to tell if a link has been retrieved (optional but useful)

Section 4: Usability for recipients

Recipients — clients, contractors, new employees — may be unfamiliar with the tool.

• [ ] Recipients do not need to create an account to retrieve credentials
• [ ] Recipients do not need to install any software or browser extension
• [ ] The retrieval interface is simple and immediately understandable
• [ ] The interface works across all major browsers
• [ ] Clear messaging explains what the link is and what to do with it
• [ ] Error messages are helpful (e.g., "this link has expired" rather than a generic error)

Section 5: Branding and professional appearance

Particularly important for agencies, IT partners, and professional services firms.

• [ ] Custom subdomain option available (e.g., secure.yourdomain.com)
• [ ] Custom logo and color scheme supported
• [ ] Custom domain links build client trust rather than introducing an unfamiliar brand
• [ ] White-label or branded option does not require significant technical setup

Section 6: Pricing and commercial terms

• [ ] A free tier is available for evaluation or low-volume use
• [ ] Pricing scales appropriately with your usage needs
• [ ] No hidden fees for compliance features (DPA, EU hosting, etc.)
• [ ] Month-to-month billing is available (no lock-in)
• [ ] Clear terms of service with no unexpected data usage clauses
• [ ] The vendor is an established organization with a track record

Section 7: Integration and API

Relevant for organizations with more complex workflows.

• [ ] A public API is available for programmatic credential sharing
• [ ] The API is documented with clear examples
• [ ] Webhooks or callbacks are available for delivery confirmation
• [ ] Integration with existing tools (ticketing systems, password managers) is possible

Note: API and integration features are not required for most use cases. Prioritize core security and usability first.

Section 8: Support and reliability

• [ ] Documentation covers all common use cases
• [ ] A support channel is available (email, chat, or otherwise)
• [ ] Response time for support is acceptable for your needs
• [ ] Uptime history is published or available
• [ ] There is a status page for service incidents
• [ ] Data can be exported or the organization is not locked in

Scoring your evaluation

For each tool you evaluate, count the checkmarks. Organize by section:

• Sections 1-2 are critical: Any unchecked item in these sections should be a blocker for EU organizations
• Sections 3-4 determine adoption: Tools that score poorly here will not be used consistently, regardless of their security properties
• Sections 5-6 determine fit: Match these to your organization's specific needs
• Sections 7-8 are differentiators: Important for larger organizations or specific use cases

PassTransfer against this checklist

PassTransfer scores well across Sections 1-5: EU data hosting, DPA availability, one-time retrieval with configurable expiry, no recipient account required, Dutch and English language support, and branded subdomains on the Pro plan. It offers a public API for organizations that need programmatic integration, and a free tier for evaluation.

Use this checklist to compare PassTransfer with other tools you are considering. The goal is to find the best fit for your organization — and to make that decision based on clear criteria rather than marketing claims.
