Is there a problem using multiple Vaults to save up field names and values? Quicken's PIN Vault has been working fine (modulo it's long standing program bugs) for years. And, Mozilla products have a "password manager" that does roughly the same thing.
Now, I purchased a 4GB flash drive and it came with a password manager. It seems to me the right thing to do is use the on on the flash disk so that logins and passwords, etc. move along with me. When I use a borrowed machine, I'll put in my master password and that will make the passwords and fields on the flash drive available (after 128 bit decryption).
Will the three password manager fight with each other -- which gets to memories he field/value name pairs? Which one gets to fill in values on the fly? Do I need to disable the Mozilla and Quicken password managers to the one on the flash drive takes over?
