Prototype sharing can feel harmless because it is “just a preview,” but prototypes may still reveal product plans, client work, unreleased UI, pricing, data, or brand strategy.
For teams working on secure sharing for Figma designs and prototypes, the useful question is not just “which tool exports this?” It is “what has to be true before this asset, file, or review flow is safe to ship?” Crypto is useful because it helps turn Figma work into password-protected links, secure review assets, and private design handoff flows, but the quality still comes from a clear workflow.
What to Check
- Limit the prototype to the flows reviewers actually need to see.
- Check who can open the link and whether access should be password-protected.
- Avoid exposing unrelated pages, internal notes, or hidden future work.
- Decide whether screenshots, PDFs, or a prototype are the safest review format.
- Remove or rotate access when the review period ends.
Common Mistakes
- A prototype link can travel beyond the intended reviewer group.
- Internal comments or hidden frames may reveal more context than expected.
- Security review should happen before the link is shared, not after a concern appears.
A Practical Workflow
Crypto gives teams a safer path for password-protected prototype sharing when standard link permissions are not enough.
Start by preparing the Figma source file with real content, clear naming, and the constraints that matter for production. Then run a focused review against the checklist above before exporting or sharing. That keeps the work from turning into a last-minute cleanup job.
When This Matters Most
This matters most when the work is repeated, client-facing, compliance-sensitive, performance-sensitive, or likely to be reused by another team. One-off manual fixes can survive on memory. Repeatable production work needs a documented process.
Next Step
Use this checklist alongside the relevant Crypto tutorial or product workflow, then review Crypto when you are ready to make this process faster inside Figma.
