2FA Day is observed every February 2nd, also known as Second Factor Day or 2nd Factor Day, to promote the importance of two-factor authentication (2FA) in enhancing online security. The day encourages individuals to secure their online accounts, including bank accounts and social media, by implementing 2FA, which adds an extra layer of protection against identity theft and fraud. Common customs include spreading awareness about 2FA, helping less tech-savvy individuals set it up, and advocating for its adoption among companies that do not offer it. Celebrations may involve sharing facts about 2FA's benefits, such as its role in preventing phishing scams and automated attacks. The date was chosen for its clever connection to the name of the day, making it easy to remember.
