Bitwarden

Bitwarden is an Open Source password manager. The free version is fully featured; a paid account comes with additional storage and access to a subscription authenticator service.

How do I Use Bitwarden?

1. Go to bitwarden.com and select "create account"; select a free account to start and you can upgrade later if you'd like to.
2. Create the account using your primary email address as the login name and one long (but not complicated!) password that you are certain you can remember but is not widely shared online. For tips, see How To Create A Good Password If You Are Not A Literal Computer.
3. Set up your password hint with a good reminder; be sure to note any punctuation you added, for instance a comma to separate lines of a song or an exclamation point between words of a movie title.
4. Verify your email account with the password manager, then set up a new password for your email. You may need a phone or access to your extant 2FA tools for this step. Create a login in the password manager, add your email address, and generate a new password, then save the entry. Go to your email account, select "security" and "change password" - enter your old password to confirm then paste your new password manager generated password into the provided text boxes, and save. Log out of your email account, then log back in with your new password. You will need to do this on all of your devices, so make sure you're using a password manager that is accessible across platforms - Bitwarden is recommended for a reason!
5. Repeat the process of resetting passwords until all of them are saved in Bitwarden; you don't need to do everything all at once, but it's best to start with your primary email addresses, your banking information, and your major social media sites as soon as you can.
6. You can also migrate from previous password managers
