1. Best password managers: 1Password
This password manager from Canada does what it says on the tin: allows you to have one master password to access any online services you use regularly.
1Password has some really attractive user functionality. You can use Touch ID on your iPhone and Nexus Imprint to authorise 1password with your fingerprint for even quicker access. It stores all kinds of account details, from passwords to bank details and loyalty schemes and will autofill web forms for you once these are stored. There is an audit function for weeding out weak passwords and a password generator to replace them with.
Master passwords are end-to-end encrypted and aren't stored anywhere, so 1Password can't see it even if they wanted to and you are in control of where your data is stored, either offline, with 1Password or with a third party like Dropbox or iCloud. 1Password even open sources its encryption design so that it can be peer reviewed.
Pricing: For individuals it is $2.99 (£2.35) a month and there are family (£3.95) and work versions (starting at £3.15 per person) also available.
