Meta has been fined €91 million ($101.5 million) by Ireland's Data Protection Commission (DPC) for a 2019 breach where user passwords were stored in plaintext, violating GDPR regulations. The investigation revealed that Meta failed to secure the passwords with encryption and did not notify the DPC within the required 72-hour timeframe. The DPC found that Meta also failed to document the breach adequately. Despite Meta's claims that no abuse or improper access occurred, the DPC emphasized the significant risk posed by storing passwords in plaintext. This penalty is part of a series of fines against Meta, totaling over €2 billion for various GDPR violations.
