App passwords: Bluesky's built-in answer to third-party tools
Bluesky designed for automation from day one. Instead of registering developer apps, you create an app password (Settings → Privacy & Security → App Passwords) — a limited credential you can revoke any time without touching your real password.
SparkSocialHq uses the app password once to open a session, stores only the resulting session tokens (encrypted), and never stores the password itself.
What a Bluesky post can contain
The 1 MB image cap trips people up more than the character limit; the composer validates both before you publish.
- ✓ 300 characters of text
- ✓ Up to 4 images, each 1 MB or less
- ✓ Posts appear instantly — no processing delay
Bluesky alongside X and Threads
Bluesky's 300-character limit sits between X's 280 and Threads' 500 — Auto-Adapt produces the right cut for each automatically from one master caption. Connecting takes about thirty seconds since there's no OAuth app approval involved.
