We love using Figma for user testing, however it poses privacy risks. In the past, I once observed someone logging back into the prototype and taking screenshots with their phone after the test ended.



  • We use Lookback and prepare a Figma prototype link to share ahead of time for each participant so we’re not scrambling beforehand.

  • We prefer this so that we don’t force our participants to sign up for a Figma account, which would seem unnecessary and would put people off.

  • I found a plugin called Crypto, but it only creates one password that can’t be changed, even when deleted and re-adding to the prototype.


We’d love to have some sort of password option we could change between participants for the public link.

@Ben_Stern had a question about the passwords. It doesn’t seem possible to have a different password for different flows and I’m trying to figure out if that’ll cause me any problems.


For context, I have a file that has multiple prototype flows, each in its own unique page within the file. And each prototype has a unique link but they all share the same password. We need only specific people to access each prototype (i.e., a single person should not be accessing all prototypes).


Is there any risk of someone accessing a different Flow in a different page within the same file through their prototype link? Because we have them on different pages, the sidebar just shows the one flow, so I’m assuming no, but wanted to check. Trying to decide if there’s any reason why I would want to create a separate file for each prototype so that they can all have a different passwords.


Hey @mariela.berrocal, unfortunately this is not possible at the moment. Community members have requested something similar, feel free to vote here for this feature request: Give unique access to specific pages.


You’re correct the only workaround for this is creating separate files and setting a password for the prototype. Thanks for sharing your feedback with us I’ll share this internally with the teams for consideration.
