1Password by Agilebits is probably my single most recommended app. I personally use 1Password to store everything from website passwords, copies of passports, social security numbers, and everything in between. Keeping all of your personal and private data in one place may seem like a recipe for disaster, but it can actually have a number of increased security benefits.
Keep your data in a vault, not your wallet!
Being able to quickly retrieve your passwords means that you don’t have to always remember them — which ultimately means that you don’t have any excuses for not choosing different passwords for each site!
