description

Manage App Store Connect authentication using the `asc` CLI tool. Use this skill when: (1) Logging in with an API key: "asc auth login", "save my credentials", "set up authentication" (2) Managing multiple accounts: "asc auth list", "switch account", "use work account", "add another account" (3) Switching the active account: "asc auth use NAME", "switch to personal account" (4) Logging out: "asc auth logout", "remove credentials", "remove account" (5) Verifying current credentials: "asc auth check", "which account am I using?" (6) Updating account settings: "asc auth update --vendor-number", "save my vendor number" (7) Explaining the credentials file format (~/.asc/credentials.json) (8) Troubleshooting 401 auth errors or "missing credentials" errors

asc auth — Multi-Account Authentication

Manages App Store Connect API key credentials in ~/.asc/credentials.json. Supports multiple named accounts with an active account that all asc commands use automatically.

Commands

login — save an account

asc auth login \
  --key-id <KEY_ID> \
  --issuer-id <ISSUER_ID> \
  --private-key-path ~/.asc/AuthKey_KEYID.p8 \
  [--name <alias>]          # optional; defaults to "default"
  [--vendor-number <number>] # optional; for sales/finance reports

• --name must not contain spaces (use hyphens or underscores, e.g. work-org)
• If no --name is given, saves under "default"
• The saved account is automatically set as active
• Saving to an existing name updates it (safe overwrite)
• Use --private-key instead of --private-key-path to pass raw PEM content
• --vendor-number is optional; saved with credentials for auto-resolution by report commands

Output — AuthStatus JSON:

{
  "data": [{
    "affordances": {
      "check": "asc auth check",
      "list":  "asc auth list",
      "login": "asc auth login --key-id <id> --issuer-id <id> --private-key-path <path>",
      "logout": "asc auth logout"
    },
    "issuerID": "abc-def-456",
    "keyID":    "KEYID123",
    "name":     "work",
    "source":   "file"
  }]
}

list — show all saved accounts

asc auth list [--pretty] [--output table]

• Active account: "isActive": true
• Inactive accounts have a "use" affordance to switch

Output — array of ConnectAccount:

{
  "data": [
    {
      "affordances": { "logout": "asc auth logout --name personal", "use": "asc auth use personal" },
      "isActive": false, "issuerID": "...", "keyID": "KEYID1", "name": "personal"
    },
    {
      "affordances": { "logout": "asc auth logout --name work" },
      "isActive": true,  "issuerID": "...", "keyID": "KEYID2", "name" 
    
  

use — switch active account

asc auth use <name>
# → Switched to account "work"

Throws accountNotFound if <name> doesn't exist. Run asc auth list first to see valid names.

logout — remove an account

asc auth logout              # removes the active account
asc auth logout --name work  # removes a specific account
# → Logged out successfully

update — modify an existing account

asc auth update [--name <alias>] --vendor-number <number>

• Updates the named account (or active account if --name is omitted)
• Currently supports --vendor-number — the vendor number used by sales-reports and finance-reports commands
• Loads existing credentials, merges the update, and saves back
• Throws accountNotFound if the account doesn't exist

Output — AuthStatus JSON (includes vendorNumber):

{
  "data": [{
    "affordances": { "check": "asc auth check", "list": "asc auth list", ... },
    "issuerID": "abc-def-456",
    "keyID":    "KEYID123",
    "name":     "work",
    "source":   "file",
    "vendorNumber": "88012345"
  }]
}

check — verify active credentials

asc auth check [--pretty] [--output table]

Shows active account name + source ("file" or "environment"). Shows vendorNumber if saved. No name field for environment credentials.

Credential Resolution Order

All asc commands resolve credentials in this order:

1. Active account in ~/.asc/credentials.json (set by auth login / auth use)
2. Environment variables: ASC_KEY_ID, ASC_ISSUER_ID, ASC_PRIVATE_KEY_PATH / ASC_PRIVATE_KEY_B64 / ASC_PRIVATE_KEY

Credentials File Format

{
  "accounts": {
    "personal": { "issuerID": "...", "keyID": "KEYID1", "privateKeyPEM": "..." },
    "work":     { "issuerID": "...", "keyID": "KEYID2", "privateKeyPEM": "...", "vendorNumber": "88012345" }
  },
  "active": "work"
}

The vendorNumber field is optional — omitted from JSON when nil. It is used by sales-reports and finance-reports commands for auto-resolution when --vendor-number is not provided.

Legacy migration: Old single-credential files ({ "keyID": ..., "issuerID": ..., "privateKeyPEM": ... }) are automatically migrated to a "default" named account on first use.

Typical Workflows

First-time setup (single account)

asc auth login \
  --key-id KEYID123 \
  --issuer-id abc-def-456 \
  --private-key-path ~/.asc/AuthKey_KEYID123.p8

asc auth check --pretty    # verify source: "file"
asc apps list              # works without env vars

Multiple accounts (personal + work)

# Add accounts
asc auth login --key-id K1 --issuer-id I1 --private-key-path ~/.asc/personal.p8 --name personal
asc auth login --key-id K2 --issuer-id I2 --private-key-path ~/.asc/work.p8 --name work

# List all
asc auth list --pretty

# Switch
asc auth use personal
asc apps list   # now uses personal account

asc auth use work
asc apps list   # now uses work account

Save vendor number for reports

# During login
asc auth login --key-id K1 --issuer-id I1 --private-key-path key.p8 --vendor-number 88012345

# Or add to existing account
asc auth update --vendor-number 88012345

# Now reports auto-resolve vendor number
asc sales-reports download --report-type SALES --sub-type SUMMARY --frequency DAILY

Remove an account

asc auth list              # find the name
asc auth logout --name personal
asc auth list              # confirm removal

Error Reference

Name contains spaces	Use hyphens/underscores: --name my-org
401 Unauthorized on API calls	Run asc auth check to verify active credentials
No credentials anywhere	Run asc auth login or set ASC_KEY_ID env var
