Google has issued a warning to its 1.8 billion Gmail users regarding a recent password hack, urging them to take immediate action within seven days to secure their accounts. The alert highlights the vulnerability of passwords and confidential user information amid widespread cyberattacks. In response to such threats, the National Institute of Standards and Technology (NIST) recommends replacing traditional passwords with passkeys for enhanced security. When passkeys are not feasible, NIST advises using long, unique phrases, avoiding common words or patterns, and employing password managers to improve protection. Additional guidance from cybersecurity sources emphasizes the importance of adopting stronger password practices to mitigate risks associated with the hacking of billions of passwords globally.
