Where is the new 'Secret Key' needed to sign in to 1PW when something goes wrong?

For some reason my password wasn't working. No idea why. Though, i think I accidentally changed it while needing to change another password - and, now, have no idea what my password was before. In trying to solve the problem, I used my Secret Key to try and log on but it didn't work. I went through the Help bit but still couldn't get in. Frustrated, I typed in the URL and when I clicked on the sign-in, not typing anything, I was in. I had seen something about the new (forget what it is called) that started with 1PRK. I found where to set that up it up. I'm in for now and can get in manually typing the URL, though haven't tried this morning. Deleteing and starting over is not an option. I have so many.
