In general, it is working. It’s possible that there is a configuration problem with your Particle account that is preventing the email from going out. The best way to resolve this is to submit a support ticket and we can check that and provide the reset password link.
These are the generic help instructions, which probably won’t help your situation, but may help someone who finds this post through search:
I prefer to reset passwords through https://build.particle.io.
If you are automatically logged in and do not know your password, select the Settings (gear) icon in the lower left of the window and then select the Log Out button.
Then, in the log in screen, you can use the Forgot Password link.
Note that the password reset emails will come from email@example.com, not from the regular firstname.lastname@example.org so they may end up in your spam/junkmail folder.
If you open the reset password link and get an empty page, you likely have corrupted saved session information. A few ways to solve this include:
Opening the reset password link from the email in an Incognito or private browsing window, which doesn’t used the saved session cookie.
Clearing the cookies and saved local data in your browser.
Opening the link in a browser other than the one you normally use.
