Yahoo has now automatically rolled out HTTPS for its mail services meeting a January 8 deadline it had set for itself last year. If you visit your Yahoo mail on mobile or PC you will notice that it is now HTTPS. The new security upgrade is available as a default and will offer improved security to Yahoo mail users.
Yahoo mail’s HTTPS uses stronger 2,048-bit encryption keys to secure certificates used to protect communications between the web server and your web browser. This will make it a lot harder to decipher intercepted emails. According to Yahoo, this new security upgrade will be available on the web, mobile web, mobile apps, or email protocols like IMAP, POP, or SMTP. It will even protect email attachments, calendar, and contacts.
The upgrade to HTTPS is Yahoo’s response to increasing concern about government’s surveillance brought to light by leaks of confidential US government documents by former NSA contractor, Edward Snowden that showed a systemic harvesting of emails and internet traffic by the US government.
