It is strongly recommended to use a new, strong, password for every website or service you sign up for.
A password manager allows you to store passwords in an encrypted list. Password managers allow passwords to be synced between devices to be accessible by you anywhere, and they can be copied and pasted into browsers.
The encrypted list is unlocked by a master password. Your list will be inaccessible if this is lost.
Recommended password managers include:
BitWarden
1Password
Dashlane
F-Secure Key
KeePass
LastPass
RoboForm
