I use
1Password for all my IOS and OSX needs. One of the biggest reasons I use it is due to the fact that it syncs so well across all my devices. Very simple to use and can do so much for you. Very easy to change passwords on sites and will generate them for you as well. I have pasted a blurb from AgileBits site in regards to it.
"1Password is a password manager that goes beyond simple password storage by integrating directly with your web browser to automatically log you into websites, enter credit card information, fill registration forms, and easily generate strong passwords. Your passwords, identities, and credit cards, are just some of the confidential information that 1Password stores in one secure place, protected by the only password you will need to remember."
It is probably one of the most, if not the most recommended password manager on these forums. Do a search of the
forums and you will see there are quite a few threads in regards to password managers.
