This is from their site. It's what I would try..
Resetting Your Password
Forgot your password? No problem! From the Sign In link in the top right corner of this page, click on forgot password and follow the on-screen instructions.
We will send a password reset link and instructions to the email address associated with your LexisNexis Store account
Note: the password-reset link will expire in a few hours. Be sure to change your password right away.
After you create your new password, it will be active right away. You can use your new password to sign in from any device.
If you requested a new password, but did not receive the password reset email:
I’m sorry , what i should have said is they sent me a pin via US mail and I can not find it even though i know it’s here somewhere
Well sadly, if you can't locate it, you're probably going to need to call them.
If they can't fix it on the phone, they'll likely need to send you another pin.
I remember putting all my pins in one place !! Just can’t remember where😲
When this happens to me I sit down and visualize myself receiving another PIN.
Where would I store it...
I start with my jewelry box, gun safe, sock drawer, center desk drawer, computer passwords, file with cc agreements, other important mail, tax info, file cabinet etc...
Sbrooks1 ... I shopped seventeen insurance companies with help from am Independent Insurance Agent and all my CB's, Lexis Nexis and the rest of the world were frozen (got my updated insurance scores to boot). Wonder why I had no problems? Ended up dropping my rates by $490 annually, so it paid to shop!
