The post 2FA app Authy data breach exposes 33M users to potential phishing attacks appeared on BitcoinEthereumNews.com.

The 2FA app Authy breach exposed 33 million phone numbers, posing phishing attack risks. No accounts have been compromised yet. Twilio has already secured the endpoint and improved app security.
