Bitwarden is a free to use, open source password manager.
Unlike most password managers, Bitwarden’s free version includes syncing your passwords between all your devices (Windows, Linux, iPhone & Android) with no limits, and supports optional two factor logins. Like most password managers, you can store an unlimited number of items in your vault (logins, notes, cards, & identities) and it will easily generate secure passwords for you.
If you feel like supporting the project, Bitwarden has very low cost Pro and Family plans. Their Team and Enterprise offerings that can help you secure your entire school or school district.
