Why a “security stack” matters
No single tool protects you completely. Layers matter.
This setup is simple, affordable, and effective.
1. Password manager
A password manager:
- Generates strong passwords
- Stores them securely
- Prevents password reuse
This is the single biggest improvement most people can make.
2. Multi-factor authentication (MFA)
Even if a password leaks, MFA adds a second barrier:
- App-based codes
- Hardware keys
- Push notifications
Avoid SMS-based MFA when possible.
3. Backups
Ransomware, device failure, and accidents happen.
Follow the 3-2-1 rule:
- 3 copies of data
- 2 different media types
- 1 off-site copy
The takeaway
Security doesn’t have to be complicated. Start with these three steps and you’ll be ahead of most people.
