Pulumi doesn't support aws MFA scenarios does it?

In what way? As in can it bypass the MFA or do you mean you're being asked to enter the MFA when you run
pulumi up
?

@powerful-continent-32307 it does, yes - but you need to authenticate with MFA and retrieve a session token I can walk you through it if needed

Confirm it works fine. My team uses MFA with Pulumi all the time.

@little-cartoon-10569 for my own posterity, what's your workflow?

Once a day, I grab my 6-digit MFA value from BitWarden and pass it to a bash alias I have,
aws2fa
.
For the next 24 hours, I can use Pulumi 🙂
The alias sets up an AWS profile with the temp creds, and a fixed name. The AWS profile that I use with Pulumi uses that profile as its source.

mind sharing that alias? I've recommended
aws-vault
for this before

The alias isn't very interesting, it just invokes an image that uses this script as an entrypoint. I think a colleague got the script from an AWS or Pulumi page...
3 profiles involved: identity is the user's profile with creds that need MFA; identity-mfa is a temp profile set up with the creds returned by _get-session-token_; and pulumi is the user's profile that refers to identity-mfa and sets up the assumed role.
(Code edited to remove hard-coded account IDs, untested in this version, you may need to edit to get it to work.)
