With the arrival of iOS 15, Apple will offer greater security in the access points that users create from their iPhone or iPad, since switch from using WPA2 security protocol launched in 2004 and used by all routers (as long as they are under 15 years old) to WPA3 protocol which was introduced in 2018.
Wi-Fi Alliance introduced in June 2018, the third generation of the WPA security protocol, a version launched with the aim to simplify Wi-Fi security, allow more robust authentication and offer greater cryptographic strength. Until iOS 14, when generating an access point from our iPhone or iPad, the WPA2 protocol is used.
Apple products have been compatible with this type of connection for a few years, so we will have no problem when connecting to a network using WPA3 encryption, besides allowing us to create them from our own device.
From each to the user, absolutely nothing changes, since the experience will remain the same as until now, but with greater security. Despite recommendations to use long passwords, with upper and lower case letters, and symbols, many users still use passwords that are easy to guess for those around them.
WPA3 focuses precisely on these casesbecause a more robust password authentication is used, offering better protection to users against attempts to guess the password by third parties. In other words, brute force attacks via key dictionaries or other sources are a thing of the past for WPA3.
Another novelty offered by the WPA3 security protocol is that it offers 192-bit encryption, by 128-bit WPA2.
