How can I find my account name for signing in to the sync option

Question

I have a sync now button, but, no set up sync key, so I can't get the digits to sync to my new laptop. When I attempt on my new laptop and press the I don't have the other device key, it asks for information including my Account. I don't know where to find that name. I have the password and recovery key; just need to find the name of the Account.

You can only use pair a device if you have already setup Sync on another device because that is how pairing works: both devices need to be online and one device needs to be connected to the Sync server.<br />
The device that you want to add gives a 3x4 character pairing code that you need to enter on the device that has already Sync set up and that is currently connected to the Sync server (so you need to have both devices at hand).<br />
Then the Sync server uses this pairing code to connect to the second device and passes the name and password and Sync key from the first device that has Sync set up to that second device that you want to add.
Enter all details like the account name (email address) and password and the 26-character Sync key manually to connect to an existing sync account instead of using the 12-character code to pair a device if pairing isn't possible.
# open "Firefox > Set Up Sync..." or "Tools > Options > Sync > Set Up Firefox Sync"
# click "I Have an Account"
That brings you to the "Pair a Device" window that shows a 12-character code that you can enter on another device that has Sync set up.
If that isn't possible then click "I don't have the device with me" at the bottom to enter the account settings (email, password, sync key) manually.
