Banks have deployed much more secure systems than SecureID, and there
have been successful attacks against them.
SecureID might be helpful if you want to differentiate your product
between automatic and manual use, but it doesn't do anything to
authenticate the party you are relaying information to. But it's
useless in a phishing context. If you want a token solution, at least
use something that factors in transaction-related data.
