Update Your Software
Turn on Automatic Updates for your operating systems (Windows, MacOS, Linux), browsers, and apps.
Use a Password Manager
Don't reuse your passwords or save them in your browser. Invest in a password manager like 1Password.
Use a Longer Phone PIN
4-digit PINs are easy to guess. Use a 6-8 digit PIN to enhance your security. After all, your phone holds your most valuable secrets.
Be Cautious With Email
Sometimes friendly looking email can contain malware. Don’t open attachments or links until you verify by phone or private messenger that they’re legit.
Back Up Your Data x2
If you backup to the cloud, do it with a secure provider like CrashPlan. If doing it yourself, use two hard drives (one away from your computer). If you can, do both.
Use an Encrypted Messenger
Whenever possible, avoid using SMS messaging. Instead, use an end-to-end encrypted private messenger.
Lie on Security Questions
Hackers can guess (or learn) the answers to security questions. Save fake answers (i.e. Maiden Name? 'Cheerios') in your password manager so you don't forget.
Get a Fake Phone Number
Avoid using your real phone number whenever possible. Use a disposable numbers from a service like Hushed. If things get spammy, ditch it for a new one.
Don't Upload Your Addresses
Some services like Facebook and LinkedIn want your contacts to make connections easier. Don't do it. Keep your Address Book out of third-party services.
Opt-out of Cloud Records
Some doctors and schools are putting patient and student records in the cloud. Opt-out of this whenever possible. Keep sensitive data as contained as possible.
Keep Learning & Stay Vigilant
Being secure takes work and practice. Apps can help, but changing your mindset is more valuable than changing your tools. Keep learning & help others along the way.
