Password Managers
It's a good idea to use a different password for different services. That way, if one of those services is compromised, it only affects that service.
If you use the same password everywhere, then you should change it everywhere after a security breach. Probably not going to happen.
If you use different passwords for different services, it becomes impossible to memorize all of them. Password managers help track all of the different passwords in a secure fashion.
Encrypting a collection of passwords is necessary if you're going to store them digitally. Good solutions exist for helping you meet this goal.
KeePass

KeePass Password Safe
KeePass is one of the older open-source solutions for tracking passwords. There are clients available for most platforms.
KeePass stores the encrypted password database locally. The tricky part is keeping your key database in sync across multiple devices. Keepass doesn't have that functionality built in. I prefer to keep the database file stored locally rather than in a cloud based service. I use git to synchronize it across devices.

Desktop
KeepassXC is an updated fork of KeepassX. KeepassX is a good cross platform option.
sudo apt install keepassxcsudo apt install keepassxcTo copy a password to the system clipboard, do not open the entry details. Ctrl-C is enabled on the find / filter list. It's not available in the details.
Merging databases
It is possible to open one copy of a database and then merge in another one via File -> Synchronize -> Synchronize with File
Very useful in the event of a git merge conflict.

Android
KeePass DX is good and open source.
KeePassXC looks like another good client

Web
KeeWeb may be a good option to try. Found it via the Open Collective site.

Older versions
sudo apt-get install keepassxsudo apt-get install keepassxKeePass.info seems to be the official desktop client

Don't like this one as much.
sudo apt-get install keepass2sudo apt-get install keepass2Bitwarden
Open Source password manager
Uses a dedicated server that you can run locally to synchronize the password database.
Written in C# Docker images are provided for the server, and there are also lighter weight clones in Ruby that are available

Seems like a great solution that may be easier to get started with for most people compared to KeePass.

It looks like there may be some issues with prompting for the password to unlock the database.
