Auth (OTP signup & login)

This is the default path in the quickstart and the one the setup-slideless marketplace skill uses. If you already have a key from the dashboard, slideless login --api-key cko_... is still available.

When to use OTP

Situation	Use
First-time setup on a new machine, new CI runner, or an agent with no prior state	`slideless auth signup-request` then `signup-complete`
Existing account, no local API key (or the key is bad)	`slideless auth login-request` then `login-complete`
You already copied a `cko_...` from the dashboard	`slideless login --api-key cko_...`

The OTP flow is two calls: one that emails a 6-digit code, one that consumes the code. No passwords, no dashboard visit. The resulting cko_ key is saved to ~/.config/slideless/config.json and set as the active profile — so slideless share, slideless list, etc. work immediately after.

Minimal (email + code + first name)

slideless auth signup-request --email you@example.com
# check inbox, then:
slideless auth signup-complete --email you@example.com --code 123456 --first-name "Alex"

--first-name is required — it’s stored as your display name and used in onboarding emails. If you omit it, the CLI fails fast with a clear error. The resulting organization is named "Alex's workspace" by default; pass --company to override or rename later from the dashboard.

With company details

Everything beyond --email + --code + --first-name is optional and mapped straight onto the new user / organization document.

slideless auth signup-complete \
  --email you@example.com \
  --code 123456 \
  --first-name "Alex" \
  --last-name "Morgan" \
  --company "Acme" \
  --description "We make widgets" \
  --brand-primary "#0a0a0a" \
  --brand-secondary "#888888" \
  --brand-accent "#e53935" \
  --tone "Pragmatic, concise, a bit dry" \
  --logo ./logo.png

Logo rules: PNG, JPEG, WebP, or SVG; max 2 MB. The CLI base64-encodes it for you.

JSON output

slideless auth signup-complete --email you@example.com --code 123456 --first-name "Alex" --json

{
  "success": true,
  "data": {
    "profileName": "alexs-workspace",
    "organizationId": "4XYwOrZ8...",
    "organizationName": "Alex's workspace",
    "apiKey": {
      "keyId": "019da6...",
      "keyPrefix": "cko_O_Q8",
      "name": "CLI default key",
      "scopes": ["presentations:write", "presentations:read"],
      "createdAt": "2026-04-19T14:21:03.000Z"
    },
    "isNewUser": true
  }
}

The raw key is stored in ~/.config/slideless/config.json; it is not echoed to stdout in the JSON response. Use this when the email already has a Slideless account but the current machine has no valid key.

slideless auth login-request --email you@example.com
slideless auth login-complete --email you@example.com --code 123456

Each login-complete mints a fresh cko_ key scoped to your existing organization and saves it as a new profile. Previous keys stay valid (you can revoke them from the dashboard if you want).

Flag	Applies to	Default
`--profile-name <name>`	both	Auto-derived from the org name
`--key-name <name>`	both	`"CLI default key"`
`--key-expires-in <days>`	both	No expiration (1–365 accepted)
`--base-url <url>`	all four	Production
`--json`	all four	Human output

Signup-specific:

Flag	Default
`--first-name <name>`	Required. Your first name. Used as display name + onboarding greetings.
`--last-name <name>`	—
`--company <name>`	`"<first-name>'s workspace"`
`--description <text>`	—
`--brand-primary <hex>`	—
`--brand-secondary <hex>`	—
`--brand-accent <hex>`	—
`--tone <text>`	—
`--logo <path>`	—

Rate limits

Resend cooldown: 30 seconds between OTP requests for the same email.
Abuse caps: 20 OTP requests per email per hour; 60 per IP per hour.
Code lifetime: 10 minutes.
Brute-force lockout: after 5 bad codes, the server deletes the record and makes you request a fresh one.

Error codes

Every failure returns this shape (both in --json output and in the structured log of the human renderer):

{
  "success": false,
  "status": 409,
  "error": {
    "code": "USER_ALREADY_HAS_ORGANIZATION",
    "message": "This email already has an organization.",
    "nextAction": "Run `slideless auth login-request --email you@example.com` to get a new API key instead."
  }
}

The nextAction field is designed to be acted on programmatically. For example:

slideless auth signup-complete --email ... --code ... --first-name ... --json \
  | jq -r 'select(.success == false) | .error.nextAction'

Code	HTTP	Meaning	`nextAction`
`EMAIL_REQUIRED` / `EMAIL_INVALID`	400	Missing or malformed `--email`	Pass `--email <valid@email>`
`OTP_RESEND_COOLDOWN`	429	Hit the 30-second cooldown	Wait `details.retryInSeconds`, retry
`EMAIL_RATE_LIMITED` / `IP_RATE_LIMITED`	429	20/hour per email or 60/hour per IP exceeded	Wait up to an hour
`USER_ALREADY_HAS_ORGANIZATION`	409	Signup for an email that already has an org	Switch to `login-request`
`USER_NOT_FOUND`	404	Login for an email with no account	Switch to `signup-request`
`USER_HAS_NO_ORGANIZATION`	409	Login for an account that somehow has no org	Switch to `signup-request`
`OTP_NOT_FOUND`	404	No pending code (never sent, or already consumed + expired)	Run the matching `-request` first
`OTP_EXPIRED`	410	Code older than 10 minutes	Request a fresh code
`OTP_INVALID`	400	Wrong 6 digits	Re-read the email; `details.attemptsRemaining` shows what’s left
`OTP_ALREADY_USED`	409	Code consumed in an earlier call	Request a fresh code
`OTP_LOCKED_OUT`	429	5 bad attempts on the same code	Request a fresh code
`OTP_PURPOSE_MISMATCH`	409	Signup code used for login or vice versa	Run the matching `-request`
`USER_FIRST_NAME_REQUIRED`	400	Missing `--first-name`	Pass `--first-name "<your first name>"`
`USER_NAME_TOO_LONG`	400	`--first-name` or `--last-name` over 60 chars	Shorten the offending name
`COMPANY_NAME_TOO_LONG`	400	`--company` over 100 chars	Shorten or omit
`BRAND_COLOR_INVALID`	400	Non-hex brand color	Use a 6-digit hex (`#1a2b3c`)
`LOGO_TOO_LARGE` / `LOGO_INVALID_FORMAT` / `LOGO_DECODE_FAILED`	400	Logo fails size/format/decode validation	Use a PNG/JPEG/WebP/SVG under 2 MB
`INVALID_EXPIRES_IN_DAYS`	400	`--key-expires-in` outside 1–365	Omit or pick a valid value
`INTERNAL`	500	Backend error	Retry in a few seconds

What’s saved locally

After a successful signup-complete or login-complete:

The raw cko_ key, its prefix, scopes, keyName, org id/name, and createdAt are written to ~/.config/slideless/config.json (mode 0600) as a new profile.
That profile is marked active.
Subsequent commands (slideless share, slideless whoami, slideless list, …) pick it up automatically.

Nothing is logged to shell history (the OTP code is an argument, not an env var, so it only appears in your terminal scrollback until you clear it).

Single-organization rule

A Slideless account has exactly one organization. Two consequences:

signup-request refuses (USER_ALREADY_HAS_ORGANIZATION) if the email already owns one. The returned nextAction tells you to switch to login-request.
Re-running signup-complete after an org exists would try to create a second one; the backend blocks it at both the endpoint and the createOrganization level.

If you need access to the same org from a different email, use the dashboard’s team-invite flow.
