We are a few weeks into the Prototype Beta and have received some great feedback from users about password-protected Figma files. To use our Prototype testing tool, you currently need to set your Figma file to public while importing. However, we understand that doesn’t work for every organization and their internal user guidelines.
​
​How are we fixing this?
The first fix will enable customers to use password-protected surveys and keep their files private (except when initially importing their prototypes). Our first cut of this should be out in the next week or so. We will update the app's instructions and provide further help documentation on how to do this in the product.

In the coming weeks, we will be releasing a more sophisticated change in how we allow customers to authorize Optimal to access their Figma accounts using Figmas oAuth. With this release, you will be able to keep your Figma file private while setting up your study. Optimal will only retrieve data about the specific file you are importing; we won’t retrieve data about your team, other projects, users, etc. The endpoints that Optimal will request from Figmas REST API during import are GET file and GET image.

This will be a chunky piece of work, but the team is on to it now. We will keep you updated on this release and other improvements as they come.

To import your Figma file, Optimal will need to retrieve images of the frames in your prototype. In order to do this you will need to provide Optimal with access to the design file itself, not just the prototype preview.

Your design file must allow edit or view access to ‘anyone with the link’ and must not be protected by a password during import.

You can turn the Figma file back to private once it is imported and add a password. However, if you want to resync at any time, you must make the study public again while doing so.

If you have a password protected prototype, in the meantime, you must supply this password to your participants. We suggest doing this both in your recruitment communications and the study welcome message or instructions or in the task copy itself.
