Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

Convert AWS IAM credentials to AWS SMTP credentials

If you do, or want to, use AWS to deploy your apps, you will end up using AWS SES via SMTP when you're launching an app that sends out emails of any kind (user registrations, email notifications, etc). For example, I have used this configuration on various Ruby on Rails apps, however, it is just basic SMTP configurations and crosses over to any framework that supports SMTP sendmail.

There are two ways to go about this:

• EASY WAY: Create an SMTP user via AWS SES [http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html#smtp-credentials-console]
• NOT SO EASY WAY: Create an SMTP password for an existing IAM user [^^ Same link scroll down]

Luckily, you found this MD file and the NOT SO EASY WAY is suddenly copy-pasta... sudo yum....

#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault
