OneFile's Keychain is a password manager for all your OneFile accounts. Instead of having to remember several usernames and passwords, you just have to remember one username (your email address) and one password to access your Keychain.
It also allows you to create a free CPD profile, as well logging in using single sign on via Facebook or Office 365.
Once you've created a Keychain and linked all of your accounts, you can quickly log into each account with just one click.
