Issue description

I have an issue when my aws profile uses an MFA device. Each time I try to enter a digit of the mfa code, it appears twice on the screen!! and as a result I have an error that tells me that the MFA code is invalid! For example if i enter the mfa code 123456, I can see 112233445566 on the screen (as you can see in the command output sample.

My profile configuration (in .aws/config

[profile xxx]
role_arn=arn:aws:iam::XXXX:role/roleName
source_profile=default
mfa_serial=arn:aws:iam::XXX:mfa/iamUser

Service configuration (serverless.yml) content

service: xxx
useDotenv: true

provider:
  name: aws
  runtime: nodejs14.x
  profile: ${env:AWS_PROFILE, self:custom.defaultProfile}
  stage: ${opt:stage, self:custom.defaultStage}
 ...

Command name and used flags
