# Account & profile

## Sign-in options

Skill3D uses [Dynamic](https://www.dynamic.xyz/) for authentication. Depending on your device and settings you can:

* Sign in with **email** (OTP)
* Connect a **wallet**
* Use a **passkey** when available

## Profile

Open your profile from the session header avatar / account control to see:

* Identity and connected methods
* Credit balance (wallet drawer)
* XP / progress where enabled

## Credits & milestones

| Data                    | Where it lives                                         |
| ----------------------- | ------------------------------------------------------ |
| Credit balance & ledger | Your account on Skill3D servers                        |
| Verified milestones     | Your account (server-side audit)                       |
| Active chat thread      | Browser session (survives refresh; archive to History) |

## Switching devices

Sign in with the **same email or wallet** on another device to keep credits and milestones. Local chat History on one device does not automatically sync to another.

## Sign out

Use the account menu to sign out. Ending a coaching session (Exit) archives the conversation and returns you to the marketing site; it does not always sign you out of Dynamic.
