I understand that in order to log into my Synchronization on a new device, I need to enter my passphrase. I've tried and failed, and am aware that resetting it will clear all the data in the Sync cloud, which I want to avoid.

What I am wondering is: can one find out when they made their passphrase? I think that knowing the year I made mine would help me to figure out what phrase I set up.

Thanks!
