F-Secure KEY is a solid password manager that should satisfy the needs of most users. Upgrading to the premium version allows you to sync up your devices so you don’t have to add your passwords manually every time on all formats. Unfortunately, there aren’t any coupons to make further savings on F-Secure KEY’s premium package but you can cut your costs by signing up for 24 months instead of 12 months so you’ll pay just $27.99 a year, which is the equivalent of $2.33 per month and saves you 15% in the process.
