I have tried to log in with the one-time pin code about 10 times & it will not
let me in.

Dear BrickLink members,
Following the examples of other online marketplaces with regards to security
features such as OTP, we have decided to change the current OTP opt-in feature
to an opt-out feature. This means that sellers will have this feature enabled
automatically in their store settings and will be able to opt-out if they so
desire.
We highly encourage sellers to keep OTP enabled for added account protection.
Additional safety measures may include changing your passwords regularly and
having separate passwords for all your online accounts.
