Is Barclay's Pinsentry part of RSA SecureID - and compromised?

No, RSA SecurID is a quite different technology.
An RSA SecurID token is physically a standalone object, about 2" * 1"
* 1.2", with LCD showing a 6 digit number that changes every minute.
Each token has a unique serial number, and maybe secret customer
identification number for each company that uses the system, that are
the base deriving the displayed number. (Details are not published by
RSA.) The token serial number is registered for user with the
company, and then the remote user identifies herself with both a
password or PIN (something she knows) and the currently displayed
number (something they have). Hence is the basis of so called two
Speculation about RSA SecurID being broken is guessing that some
secret design aspects of the system have been stolen, or maybe a list
of companies using SecurID & the embedded per company secret seed
numbers. Even if true a bad person would still have to have some very
specific information for it to be of use: a user's account, their
normal password and/or PIN, and the serial number of the SecurID
