If security is as crucial for you as it is for me, 1Password is a step in the right direction. I have been using it for several years now, and I am glad I did.
All my passwords are different, and there is no way I can remember them all. 1Password provides a way to have access to all your passwords via its apps on your phone, pad or online and with the integrated Watchtower app, which alerts you of websites that might be compromised and advice you to change your password, it even smells secure 🙂
It runs on all big platforms, mobiles and pads and syncs seamlessly on all connected devices. Backup is done via their secure cloud servers, which also keeps all devices in sync.
This is one of the essentials I would advise everyone to invest in.
