Remembering all your passwords is difficult enough, but synchronising the data across your devices is even more complicated. If you store a unique password for each website, as you're wisely told to do, then you need to be able to login using both your desktop and smartphone. Problem is, login with an iOS device and it might default to Safari, whilst you prefer Chrome on your Mac.
We use 1Password to keep our password synchronised, but there a number of other options including LastPass, Buttercup and Bitwarden, amongst many others.
McAfee has released its own password management system and it's rather impressive, in places.
McAfee TrueKey is a download for either your Mac or PC (Windows version supplied here) and it installs as an extension for your web browser: Chrome, Firefox, Edge or Internet Explorer. But not Safari. And that causes us all kinds of issues as a Mac/iOS user as it means that if we need to use Safari, True Key is not supported, so you can't access your passwords. At least with 1Password it's a standalone Mac application, separate from your web browser. True Key simply tries to open your web browser. This is a huge flaw for any Mac user wanting to switch to True Key.
True Key is like any centralised password manager. Once installed, every time you access a website, it automatically stores the password (you can choose for it not to store a website password on a site by site basis). Next time you go back to the website, True Key logs you in automatically when you access from a trusted device. True Key will also analyse your face from your webcam and store this for login, but on a Mac this didn't work properly for us either. We couldn't log back into True Key with our stored face and had to keep readjusting our webcam position to analyse. It still failed.
On an iOS device, as long as the option is supported (think iPhone X/XS/XR which lack fingerprint support), you can also login with your finger.
True Key will also offer to generate secure passes you can use, it will store your notes securely and even offer to store your credit cards, password, ID cards and other personal information.
Another issue we found is that True Key disables your web browser password system and takes over. But this introduces a strange flaw - we forgot our obscure 'master password' and as True Key wouldn't recognise our stored face, we couldn't log back in as we'd forgotten the stored (in True Key, ironically) 'master password'.
The free True Key will only store 15 passwords, which is very limiting. If you want to store more than 15 passwords (we think that applies to everyone), then you need to buy True Key Premium, which is $19.99/year and will store up to 10,000 logins/passwords.
