## Duo Settings
## You need to configure all options to enable Duo support
## Create an account and protect an application as mentioned in this link (only the first step, not the rest):
## https://help.bitwarden.com/article/setup-two-step-login-duo/#create-a-duo-security-account
## Then set the following options, based on the values obtained from the last step:
# DUO_IKEY=<Integration Key>
# DUO_SKEY=<Secret Key>
# DUO_HOST=<API Hostname>
## The Aplication Key needs to be randomly generated. Recommended at least 40 characters in base64.
## Example command to generate it: 'openssl rand -base64 48'
## Note that this shouldn't change between runs.
# DUO_AKEY=<Application Key>
## After that, you should be able to follow the rest of the guide linked above,
## ignoring the fields that ask for the values that you already configured beforehand.
