LastPass x AWS x SAML = Headache for awscli?

lp-aws-saml allows you to use the awscli on your machine when your login to the aws console is via LastPass SAML login only.

It even supports 2FA and Yubikey OTP for your LastPass login and will store your LastPass session in ~/.aws/lp_cookies so you do not have to type the password every time you need new credentials.

$ lp-aws-saml -h
