Site infra team has changed the trust policy in tvlk-prod account granting access to ReadOnly role.
Previously user from tvlk-dev account could assume ReadOnly role in tvlk-prod account without MFA enabled in their account.
We changed the policy to require MFA when assuming role with access to tvlk-prod account.
If you failed to assume ReadOnly role in tvlk-prod, please enable MFA for your IAM User and relogin before assuming role.
Thank you.
