Use the “passwords” feature to check if one of yours is compromised. If it shows up, never ever reuse those credentials. They’ll be baked into thousands of botnets etc. and be forevermore part of automated break-in attempts until one randomly succeeds.


Yes and no; they have their own issues:

I assure you, the rare security issues for password managers are far preferable to managing compromises every couple weeks.
I’ve only really been in one breach. This one is actually a breach of a “security firm” (incompetent idiots) who aggregated login data from the dark web themselves, essentially doing the blackhats’ work for them.
This is also EXACTLY why requiring online interactions to be verified with government ID is a terrible idea. Hackers will similarly be able to gain all possible wanted data in a single location. It’s simply too tempting of a target not to shoot for.
You’ve only been in one breach that you know about so far!
If you think you’ve only been in one breach, you’re probably mistaken or very young. I don’t know how many breaches I’ve been involved in, but it’s at least double digits.
I’m American, and my Social Security number has been leaked multiple times. Each time I’ve done everything possible to secure my accounts (random passwords, TOTP 2FA where possible, randomized usernames, etc), yet there’s always a new breach that impacts me.
I’m not too worried though. My important accounts are pretty secure. I use one of the few banks (brokerage actually) that provides proper 2FA. My email and password manager use 2FA. My credit is frozen. Breaches happen, the important thing is to limit the impact of a breach.
A password manager is still a good idea, but you have to not use a hacked one. So only download from official sites and repositories. Run everything you download through VirusTotal and your machine’s antivirus if you have one. If it’s a Windows installer check it is properly signed (Windows should warn you if not). Otherwise (or in addition) check installer signatures with GPG. If there’s no signature, check the SHA256 OR SHA512 hash against the one published on the official site. Never follow a link in an email, but always go directly to the official website instead. Be especially careful with these precautions when downloading something critical like a password manager.
Doing these things will at least reduce your risk of installing compromised software.
