Originally described in 1984 in RFC 918, it was followed by POP2 in 1985 in RFC 937. POP3 is one of the oldest mail protocols around. (If you have an easy-to-crack password, an attacker can use dictionary attacks to eventually guess your password.) The ins and outs of POP3 and IMAP As long as those mail servers have to support these older protocols, attackers can use any number of brute force attacks and other devious methods to break into your mailbox. You might think POP access using basic authentication should be secure enough, assuming you don’t click on malicious links, do keep your computer up to date, and use a secure browser.Īs it turns out, attackers can use weaknesses built into this older protocol to break into online mail servers. So just what is basic authentication? It’s what we’re used to already - access by username and password to old-fashioned Post Office Protocol or “pop” email, where you log in and download emails to your computer.
It had planned to disable authentication earlier this year before realizing it couldn’t do so without impacting businesses and users still struggling amid the pandemic.

A second change scheduled for next year may have a bigger impact on how you connect your email client - and may affect other email apps, too.īecause it could affect many users and businesses, Microsoft is giving everyone fair warning - a year in advance. 1 - it’s important to remember this isn’t the only change coming for Outlook.
