 Be sure to use the unmodified release binary you downloaded from Github above (i.e., `v2.1.2-passport.bin`) that still has our official signatures, as Passport will only allow you to install firmware that has been signed by at least two members of the Passport team.

 ## Conclusion
 
 We want to close out this guide by thanking our fantastic community, many of whom have tested out reproducibility or let us know when they run into any issues along the way. Open source and the verifiability and transparency it brings are core to our ethos at Foundation, and the ability to reproducibly build firmware for Passport is a core outpouring of that.
