    • start with regular sms
    • if you're slightly more into Tech, you can use totp apps like Microsoft Authenticator or Google Authenticator or Yubikey Authenticator
    • make a backup of your codes, make a backup of the app! losing the app without backup means: no access to your service
  • Use a password vault to help you remember all the different strong passwords for different services and you're only human
    • secure that password vault like hell!


  • When things go south: make sure you have OFFLINE backups of all your useful data
  • Take a backup of your online services! Gmail/Google exports, Hotmail exports, Facebook, Twitter, Github, ... If it's compromised it's GONE. GDPR helps here by enforcing services to grant you access to your data.
