Quick start

# Set a secret
$ monosecret set DATABASE_URL --provider keyring
Enter value for DATABASE_URL: postgresql://localhost/mydb
✓ Secret DATABASE_URL saved to keyring

# Get a secret
$ monosecret get DATABASE_URL --provider keyring
postgresql://localhost/mydb

# Run with secrets
$ monosecret run --provider keyring -- npm start

Setup

• macOS: Keychain
• Windows: Credential Manager
• Linux: Secret Service (GNOME Keyring, KWallet)

Linux prerequisites

Linux only - install if missing:

# Debian/Ubuntu
$ sudo apt-get install gnome-keyring

# Fedora
$ sudo dnf install gnome-keyring

# Arch
$ sudo pacman -S gnome-keyring

Configuration

URI format

keyring://[folder_prefix]

• folder_prefix: Optional path prefix supporting {project}, {profile}, and {key} placeholders. Defaults to monosecret/{project}/{profile}/{key}.

URI examples

keyring
keyring://shared/{profile}/{key}

Project configuration

monosecret.toml

[providers]
local = "keyring://"

[profiles.default]
DATABASE_URL = { description = "Database URL", providers = ["local"] }

Storage model

Each secret is stored under monosecret/{project}/{profile}/{key} as the keyring service, with the current system username as the account. Project and profile names keep convention secrets isolated.

Use existing secrets

A secret’s ref field names an exact keyring entry instead, useful for reading a credential another application already stored: item is the service, and the optional field is the account (defaults to the current system username). Reads and writes target that entry in place.

[profiles.default]
API_TOKEN = { description = "Token", ref = { item = "com.example.app", field = "me@example.com" }, providers = [
  "keyring",
] }

Advanced configuration

Shared secrets

By default, secrets are stored under monosecret/{project}/{profile}/{key}, which isolates them per project. To share secrets across projects, use a custom folder prefix via the URI:

~/.config/monosecret/config.toml

[defaults.providers]
shared = "keyring://monosecret/shared/{profile}/{key}"

The URI supports {project}, {profile}, and {key} placeholders. By omitting {project}, multiple projects can read and write the same keyring entry:

# monosecret.toml (in project-A and project-B)
[profiles.default]
ARTIFACTORY_USER = { description = "Artifactory user", providers = ["shared"] }

Both projects will resolve ARTIFACTORY_USER from keyring service monosecret/shared/default/ARTIFACTORY_USER.
