Facebook Plain Text Password Storage Controversy
Facebook Plain Text Password Storage Controversy refers to the March 2019 disclosure that Facebook stored hundreds of millions of user passwords in unencrypted, readable form on internal servers, where roughly 20,000 employees could search them1. The story broke via KrebsOnSecurity and was confirmed the same day by Facebook, adding to a long run of privacy scandals hitting the company that year2.
Overview
The Facebook Plain Text Password Storage Controversy is the March 2019 security scandal in which Facebook admitted it had been keeping vast numbers of user passwords in unhashed, human readable form inside its own data storage systems1. Instead of being scrambled with the usual cryptographic hashing and salting, the passwords sat as plain strings that any of roughly 20,000 Facebook engineers and developers could search for through internal tools3.
The issue spanned Facebook proper, Facebook Lite (the stripped down app aimed at users with poor connectivity), and Instagram, with archives of readable passwords dating back to 20121. Estimates of who was exposed ran from 200 million to as many as 600 million accounts, making it one of the largest password handling failures ever disclosed by a major consumer platform5. The story fed directly into the wider narrative that 2018 and 2019 were catastrophic years for Facebook's privacy record after Cambridge Analytica and the 50 million account breach5.

How to Use This Meme
This is a news event rather than a template, so there is no image macro or catchphrase to reproduce. It is most often referenced in two ways online: as shorthand in security discussions when arguing why plaintext password storage is inexcusable at any scale, and as a punchline in Facebook privacy jokes, usually stacked with Cambridge Analytica and the 2018 access token breach to show a pattern of failures5. Security professionals commonly cite it as a case study in why hashing and salting are baseline requirements, and journalists still bring it up whenever Facebook or Meta announces a new privacy initiative3.
