Protip for the room: Use a password manager with a unique password for every service. Then when one leaks, it only affects that singular service, not large swaths of your digital life.

For me, if this happens, it has no impact since almost every page i sign up to has a unique password. The most important ones has mfa as well.

Use a password manager. Simple.

Stuffing? Just in time for the holiday season!

Why did you censor yourself in the title?

The thing about this one is no one seems sure of the source (it appears to be from multiple sources, including infostealer malware and phishing attacks), so you don't know which passwords to change. To be safe you'd have to do all of them.

Some password managers (e.g. Bitwarden) offer an automatic check for whether your actual passwords have been seen in these hack databases, which is a bit more practical than changing hundreds of passwords just in case.

And of course don't reuse passwords. If you have access to an email masking service you can not only use a different password for every site, but also a different email address. Then hackers can't even easily connect that it's your account on different sites.

God fucking dammit, I fucking hate seeing people self-censor themselves on the internet.

Let's make a master list of all the emails leaked with their passwords, what could go wrong?

Proud that my only pwned password is three decades old.

Yeah gotta make sure you never use the same password in multiple places, use a password manager.

Comprised of email addresses and passwords from previous data breaches,

So these are previously “hacked” data, and now the aggregator has been hacked?
