Some thoughts on Amazon's 2FA

A screen from Amazon showing how to use 2FA

Amazon now let you secure your account with Two-Factor-Authentication (2FA). This means you can log on with a one-time password which changes every minute.

Scaling Is A Human Problem Too

a slack icon saying kill me please

This morning I received an email which made my heart sink. In order to co-ordinate things better, we'd like to invite you to our exclusive Slack Channel!

Don't Use Colour To Indicate Binary States
