Basic HTTP Authentication¶
SWS provides 'Basic' HTTP Authentication Scheme using an
This feature is disabled by default and can be controlled by the string
--basic-auth option or the equivalent SERVER_BASIC_AUTH env.
The format to use is the following:
Both are separated by a
: (punctuation mark) character.
Only the password must be encoded using the
BCrypt password-hashing function.
As an example, we will use the Apache
htpasswd tool to generate the
htpasswd -nBC10 "username" # New password: # Re-type new password: # username:$2y$10$8phm28BB4YpKPDjOpdTT8eUcfVDw0xc85VZPxg2zae1GR8EQqus3i
Password Security Advice
The password verification happens at runtime but its verification speed depends on the computing time cost of
bcrypt algorithm used.
For example, the
htpasswd tool supports a
-C argument to adjust the
bcrypt's computing time.
Using a higher value is more secure but slower. The default value is
5 and the possible values are ranging from
Docker Compose Advice
If you are using
SERVER_BASIC_AUTH env via a
docker-compose.yml file don't forget to replace the single
$ (dollar sign) with a
$$ (double-dollar sign) if you want those individual
$ dollar signs in your configuration to be treated by Docker as literals.

Finally, assign the credentials and run the server.
