External MFA to issue TOTP not supported #566
Description
op CLI version
2.32.0
Goal or desired behavior
Use the shell plugin with MFA but with a 3rd party TOTP provider (e.g yubikey).
Not being locked into 1password as OTP provider.
Current behavior
It is not possible to issue OTP from within an external hardware token using 1 password.
This is also referenced in official forums of 1 password, seemingly was possible in the past:
https://www.1password.community/discussions/developers/aws-cli-plugin-is-not-supporting-external-otp-anymore/97110
The sourcecode explicitly mentions this behavior as well:
shell-plugins/plugins/aws/sts_provisioner.go
Line 232 in 49810df
