  • 2FA or Not 2FA
    You’d think so. But over and over plain text leaks of passwords is the practical reality of the modern internet. A disgruntled staff member, poor tech practices or someone working out a way to get in and get access. The https://haveibeenpwned.com/ project regularly shares new breached datasets. Reusing passwords across websites without MFA is just not not not recommended in 2025. - Source: Hacker News / about 1 month ago
