Account and Device Security
This module builds the four lines of defence for your online accounts: strong passwords, two-factor authentication, phishing awareness and a ready account recovery plan. The lessons proceed with concrete steps, not scare tactics.
In this module
- You understand the logic of long, unique passwords and can start using a password manager
- You can enable two-factor authentication on your important accounts with the right method
- You can recognise phishing messages by their patterns and respond correctly
- You can keep your recovery details current and reduce the risk of being locked out
The logic of layered defence
Account security is not one magic measure but a set of complementary layers. A strong password is the first door; two-factor authentication is the second lock that holds even if the password is stolen; phishing awareness neutralises the attacker's favourite route — deception; and a recovery plan keeps the way back open if access is lost despite everything. When one layer is weak, the others carry the load; that is why four reasonable layers beat one perfect measure.
The order of the lessons
The module moves from the attack surface toward recovery. Password Security reinforces the first door. Two-Factor Authentication fits the second lock and explains the security differences between methods. Phishing introduces the tactics of deception. Account Recovery teaches you to prepare for loss of access in advance. When you finish the module, move on to the programme assessment.
