Passwords.txt: !!top!!

lost years of intellectual property after a grad student stored server credentials in passwords.txt on an FTP-accessible directory. Attackers found it in minutes and exfiltrated sensitive data over several months.

One of the most dangerous cognitive biases at play is the – the tendency to underestimate how long a task will take. Users create passwords.txt thinking, “I’ll organize these properly next week.” But next week never comes. Months later, the file still sits there, now containing dozens of updated passwords, SSH keys, and credit card numbers.

: In the event of a data breach, plain text passwords can be easily exploited by attackers.

While historically vulnerable, modern browser vaults (like Google Chrome, Apple Keychain, or Microsoft Edge) have significantly improved. They now require biometric authentication (Windows Hello or FaceID) before revealing or autofilling credentials, adding a layer of defense that a text file completely lacks. Conclusion: Delete the File Today

But the behavior is always the same:

Many people save passwords.txt in cloud folders like Dropbox, Google Drive, or OneDrive. If that cloud account is compromised (through phishing or weak passwords), the attacker searches for files with “password” in the name. Shared links can also inadvertently expose the file to the public. lost years of intellectual property after a grad

If you refuse to use a password manager, you should at least add layers of protection to your file: Never use "passwords" in the title.

Note: bcrypt is slow; only feasible if password is weak. If not cracked, use other context from passwords.txt to guess:

An 18-year-old hacker social-engineered an Uber contractor, got their VPN password, and then... found a network share containing a PowerShell script with the administrator credentials for Uber's entire Thycotta (privileged access management) system. While the file wasn't literally named passwords.txt , it was a plain-text text file containing the same information. The attacker took control of Uber’s Slack, AWS, GSuite, and HackerOne dashboards. Users create passwords

We’ve all been there. You’re juggling a dozen different logins—banking, email, streaming services, work accounts—and your brain simply cannot hold another complex password. So you do the most “efficient” thing: you open a simple text editor, type out all your usernames and passwords in neat rows, and save the file as passwords.txt on your desktop. It’s convenient, searchable, and always at your fingertips.
