For what it's worth, I use KeePass and on multiple devices.  I will summarize below.  Note, there are no costs (to purchase or recurring) for any of the following (further down on the page some items may have a cost and it is noted). These are my practices and I'm only putting them here for readers to consider when setting up their database security system. You should do what you feel is best for you.
The major benefit for using a password manager are: (1) You only have ONE password to remember, and (2) You can use Long, Complex, and Hard-to-guess passwords

1. KeePass refers to both (a) an encrypted database holding information and (b) the name of one application that can access the database.
2. A KeePass database can hold
   1. Logins and password
   2. Other information you feel useful, such as: Social Security numbers, Secret passwords (answer to “what was your first dog's name”), telephone numbers
   3. Past passwords.  Date you started to use a given password.
   4. And all of the data in the database is encrypted. 
3. There are many applications that can access a KeePass database, and the same database can be accessed from each of them.  You choose one that is available and that you find works for you.
   1. On my iPhone, I use or have used: KeePass Touch, KeePassium, MiniKeePass
   2. On Windows (a while ago) I was using KeePass2
   3. On Mac OSX I'm using KeePassXC
4. When I first started using KeePass, I would keep the database on a USB stick and copy it to/from any computer I was using to access/modify the database.  The risk of course is that the database might differ on different machines or that I might misplace the USB stick.
5. Then I started using Dropbox to hold the database.  This way I could access the KeePass database from any machine or phone that could access Dropbox.
6. Then Dropbox started restricting free use to 3 devices.  Then I switched to storing it on iCloud, and periodically copy it from iCloud to: Dropbox, pCloud, and into the Documents directory on the machine I'm using.
7. I have an entry in KeePass with a name I modify that indicates the last important change I've made to the database.
   1. For example: “Last Changed 2021 1202.1003” so I know the last change was December 2, 2021 at 3 minutes after 10.
   2. This way I can see how current a database is on the other devices and determine whether I need to update it on that device.
8. I use the KeePass application to create new entries and especially passwords for logins. My passwords are typically 14 characters or longer (upper/lower case and numbers) and the KeePass application considers them secure.
   • Here is a possible password I might use (and it's one I am not using): cqLbq2NHcuNmgU – 14 characters, upper and lower case letters, and at least one number. This one has entropy 82.06 which is “good”.
   • This one: M6dehfJRn7dz7lM82K 18 characters with entropy 101.60 and is considered “excellent”.
   • Using a password manager you can create quite long passwords
   • Using a password manager you can create secure passwords and not have to remember all of them
   • Using a password manager you have all of your access information in one spot, the encrypted file
     • (your next of kin would likely find this useful)

There are other capabilities of a KeePass password manager like autofill (it'll copy and enter passwords for you) and URL entry (it'll enter your site's URL into your browser), and more; but I do not have experience with these.

The idea for this started when I heard that someone had someone access their Facebook page. It's possible this happened because Facebook passwords were stolen but it's also that the password was guessed. Let's explore ways that passwords are compromised and how to protect your passwords without causing unnecessary effort on your part.

And is there a way to store all of your account and login information, securely, and easy to access?

  • Commonly used/easy guess passwords (password123 Password123 password ilovejohn)
  • Commonly used passwords with simple changes(p@ssw0rd !l0v3j0hn)

• Password cracking software (ophcrack, cain and able, THC-Hydra, Brutus)
• The password is stolen from a company

How long does it take to crack a password? (From Keithieopia 2017 link)

or this from Kim Komando

Yes, there are differences in time to crack, but the key is that it's best to do a 14-character mix of upper/lower letters and numbers.

You should assume that the attacker knows a lot about you: e.g., Facebook. Guessable things like the following have no business being in your password (or as one the answer to any of your recovery questions:

• Your: name, birthday, anniversary, social security number, etc
• Name, birthday, etc of your parents, friends, spouse, dogs, etc
• Sequences like 12345
• Any of the above but combined – adding guessable things together does not make them un-guessable
• Passwords you've used before, they've probably already been breached

• Change it often
• Make it hard to guess - upper and lower chars, digits, special chars. 14+ characters long.
• Watch the news for company security breaches and change password

If a human is going to guess the password then make it unhuman. Consider: a password “safe”. Here are some free alternatives. From Tech Radar, The best free password manager 2019 with updates I took from the application sites 20211007

Do a DuckDuckGo (or Google if you're still using Google) search for “Best Password Managers” and look for those with 2020 or 2021 information.

All offer unlimited login and text note storage in a secure vault protected by your master password, and can generate (and store) strong passwords.

You enter your email address and this site (https://haveibeenpwned.com/) will tell you if your email address has been picked up during a data breach and which sites. Note that it also suggests using a paid password manager system; check my advice on password managers above.

I use a combination of KeePass on my Mac, PC, iPad, and iPhone to access, create, maintain passwords and related information in a secure password safe (encrypted file). I store and access the safe using iCloud, pCloud, and Dropbox.

Note that KeePass has different applications you can use to access the password safe, as they differ by device.

While I started using Dropbox as you could access your free 5GB from any number of devices, they have restricted its use to 3 devices unless you pay. Now I am using iCloud (with pCloud as a backup) to hold the password safe as there is no limit on number of devices.

If you do not want to use the cloud (Internet storage) to save your password crypt, you can store it on your computer and use a USB stick to copy it from machine to machine and as a backup.

• KeePassXC
• Dropbox, iCloud, pCloud

• KeePass Touch
• iCloud

• KeePass2 (download directly from https://keepass.info)
• Dropbox or iCloud or pCloud

• While some apps store passwords in their space, this means it's a SPOF²⁾ – if they close or lock you out, you're SOL³⁾
• KeePass lets you decide where to store it – on your computer, on USB stick, cloud storage of your choice – and this provides a level of security, backup, and access you control
