No. Google Ourgroceries. Just try the above instructions, it will send you an additional PW to use on your PC by email. You keep your original PW.
Do I google "ourgroceries" on the phone or on the PC?
Then, which result do I click? I tried from the PC and it didn't send me a new password. It asked me if I had an account and did I remember my password. I answered yes to both and it signed me in.
I'm sure there is something really obvious, that I am just missing.
