YTMDA token not found, please authenticate using `oh-my-posh

Error message

YTMDA token not found, please authenticate using `oh-my-posh auth ytmda`

What it means

The ytm segment (YouTube Music Desktop App) requires an auth token cached under the key auth.YTMDATOKEN, obtained via `oh-my-posh auth ytmda`. setStatus throws this error when the cache has no token or the stored string is empty, meaning the user never authenticated or the token was cleared.

Solutions

1. Run `oh-my-posh auth ytmda` to authenticate and store the token
2. Ensure YTMDA (YouTube Music Desktop App) is installed and its API is enabled
3. Remove/disable the ytm segment from the prompt config if not using YTMDA
4. Check that the oh-my-posh device cache persists between sessions (not wiped on reboot)
5. If auth was run, clear cache and re-authenticate to refresh a stale token

Example fix

// before: shell config renders ytm segment without token
{ type = "ytm" ... }
// after: run once first
oh-my-posh auth ytmda

// before enabling the segment, check for the token
if _, ok := cache.Device.Get[string](auth.YTMDATOKEN); !ok {
    // prompt the user: oh-my-posh auth ytmda
}

token, OK := cache.Device.Get[string](auth.YTMDATOKEN)
if !OK || token == "" {
    return errTokenMissing // segment hides itself instead of failing the prompt
}

When it happens

Trigger: Enabled calls setStatus; cache.Device.Get[string](auth.YTMDATOKEN) returns OK=false (key absent) or an empty string. Happens on any machine/profile where `oh-my-posh auth ytmda` was never run or its cache was wiped.

Common situations: Fresh install or new machine; cache directory cleaned/deleted; token cleared after YTMDA re-install; running the prompt with the ytm segment enabled in the config but never completing the auth flow.

Understand the failure class

• Authentication and authorization failures — expired tokens, bad credentials, and missing scopes.
