Jagex Account Guardian

The Jagex Account Guardian, also known as JAG, is a security feature that provides enhanced account security which blocks unknown devices from accessing your account. It combines the technologies of IP address tracking and device recognition to authenticate a user access to logging in. Its primary aim is to prevent against phishing and hi-jacking; additionally, it discourages account sharing.

A player may choose the device(s) that they wish to grant access to for the account. Unknown devices need to pass email and security checks before access is permitted. If a player plays from multiple locations, they can add new devices at anytime and can have as many as they'd like. Devices can be given access on a temporary or permanent basis.

With the introduction of JAG, the recovery question feature was removed and replaced with a permanent recovery question system within JAG. The questions provided may not be customised, therefore the pre-set questions aim at answers that only the real owner of the account would provide. Answers may not contain capital letters. The questions choices are:
 * Secondary email address for J.A.G / account security
 * Where was your first vacation / holiday?
 * In what city or town did your mother and father meet?
 * What was your favorite place to visit as a child?
 * What is the last name of your favourite teacher?
 * Who was your first best friend – first name?
 * What is your favourite sports team?
 * What is the first book you remember reading?
 * What was the first video game you bought?
 * What was the first music album you bought?
 * What is your mother's middle name?
 * What is your oldest cousin's first name?

Unfortunately, one major drawback to the JAG security system is if the player happens to forget their own answers, or the proper spelling of an answer with no permenant device to log into. The account is effectively stuck and cannot be logged into or played at all unless the player can remember or properly guess their own JAG security answers again. Players only get three tries every 24 hours, after which the account is locked for 24 hours to all non-permanent devices.

Trivia

 * Jagex Account Guardian can be shortened to JAG, which is also shorthand for Judge Advocate General's Corps, the legal branch or specialty of a military concerned with military justice and military law of the American and Canadian militaries.
