This is a possible solution, but not a very good one, if you take security in consideration. Specially if you use the same password for the important things (say, your bank account) and for the things that do not demand a high level of security (say, your bugzilla account, or mailing list password). If one password is compromised, all of your secrets are in the open. Considering the multitude of sites and services we use that require passwords, if only one of them don't take good care of your password, you have a big problem. It's better to use distinct passwords for most important things. Also, there are services/applications that require you change your password every now and then. In this case, it's hard to keep all of your passwords synchronized when one of them have to be changed. []'s Marcelo []'s Marcelo |
