Public Links: Password Enforcement and Policy

OpenCloud provides two related controls for passwords on public links:

  1. Password enforcement for public links (whether a password is required at all).
  2. Password policy (how strong a password must be, if a password is used/required).

This guide shows how to configure both via opencloud-compose/.env.

By default, OpenCloud requires a password for public shares. You can disable that requirement globally and (optionally) still require passwords for writable public links.

OC_SHARING_PUBLIC_SHARE_MUST_HAVE_PASSWORD=false

Require a password for writable public links only

OC_SHARING_PUBLIC_WRITEABLE_SHARE_MUST_HAVE_PASSWORD=true

This setting only applies when OC_SHARING_PUBLIC_SHARE_MUST_HAVE_PASSWORD is set to false.

OpenCloud can enforce strong(er) passwords by requiring occurrences of characters across different classes. You can individually configure the minimum number of:

  • lower-case characters

  • upper-case characters

  • digits

  • special characters

that must appear in a valid password (and also set a minimum length).

Add or adjust these variables in your .env file:

Enable/disable password policy checks​

  • true = policy disabled (no complexity requirements enforced)
  • false = policy enabled (requirements below are enforced)
OC_PASSWORD_POLICY_DISABLED=false

Minimum password length​

OC_PASSWORD_POLICY_MIN_CHARACTERS=8

Minimum character-class requirements​

OC_PASSWORD_POLICY_MIN_LOWERCASE_CHARACTERS=1
OC_PASSWORD_POLICY_MIN_UPPERCASE_CHARACTERS=1
OC_PASSWORD_POLICY_MIN_DIGITS=1
OC_PASSWORD_POLICY_MIN_SPECIAL_CHARACTERS=1

Optional: Path to a 'banned passwords list' file​

OC_PASSWORD_POLICY_BANNED_PASSWORDS_LIST=""

The password policy only applies when a password is set/required for a public link.

More information is available in the developer documentation on password policy.

Edit the .env File​

Open the environment configuration file located in your opencloud-compose directory:

nano opencloud-compose/.env

Add or modify the variables from the sections above as needed, then save the file.

Restart Docker Services​

After saving the file, shut down and restart the Docker containers to apply the changes:

docker compose down
docker compose up -d
hinweis

This change applies globally to all public shares created after the restart.
