Account, licensing, and activation keys
Your account, device authorization, and model spend are three separate things. Keeping them apart avoids the "I already paid, why is it still asking me to sign in or top up?" confusion.
What each of the three covers
| Item | Purpose | Usual entry point |
|---|---|---|
| Mystilink account | Sign in, view orders, manage activation keys and Newton balance | Dashboard |
| License and Credential (activation key) | Record the entitlement and assign that device seat to the desktop app | Dashboard key list, desktop activation screen |
| Newton balance | Pays for inference on Newton-hosted models | Dashboard balance, and Newton |
With third-party BYOK, model charges are paid to that vendor; a third-party balance never appears as Newton balance. A one-time device license also does not mean unlimited use of cloud models.
Using an activation key after purchase
- Check the current license plans and device counts on the pricing page; the checkout page confirms what you are buying.
- Sign in with the account used for the purchase and open the dashboard to see the issued keys.
- Copy one available key and activate on the computer where you need it.
- On a multi-device plan, use a different key for each computer. Do not use one key on several machines.
If payment completed but the list has not updated, check the account and order status first, then contact support. Do not buy again before looking into it; see Troubleshooting.
Moving machines, resetting, and revoking
| Action | Meaning | When it applies |
|---|---|---|
| Reset device | Removes that key's device binding so it can be used on a new device | Replacing a computer or rebinding |
| Reset all keys | Old keys stop working and a new set is issued | A wholesale replacement; affects devices still using the old keys |
| Revoke | Permanently disables that key, with no recovery | Key leaked or needs disabling; the dashboard does not expose this, so contact support |
Moving machines normally only requires handling the binding of the target key; there is no need to reset everything. Unbinding a device does not migrate local profiles and conversations; to move data, make a separate backup.
Signing in is not the same as activating
Web sign-in manages account assets; desktop activation verifies a device's entitlement. Using Newton additionally requires signing in to your Mystilink account in the desktop app. Pasting an activation key alone is not a Newton sign-in.
Purchases, refunds, and keeping credentials
Current plans, prices, and scope are defined by the pricing page and what the checkout shows at the time of purchase; refunds are covered by the dedicated refund policy. Keep full activation keys and account credentials safe, and mask them in public screenshots. Support usually only needs the order details and the error message; see Contact support.
Data and privacy
The licensing service needs network access to validate devices; profile cards and conversation files live in your local workspace. With Newton, inference content is processed by Mystilink / Newton and its upstream services; with BYOK it goes to the configured vendor or gateway. Neither case can be summarized as "stored locally, therefore nothing is sent to the cloud". See Privacy and local data.
