Smart sync1. Prepare a test vault
Back up your notes and start in a separate vault. Install the Global preview plugin from the package provided for your test. Read and handle Obsidian's trust prompts yourself. Do not use a domestic package to connect an overseas account.
2. Sign in
Open Settings → Smart sync → Sign in. Choose Google, GitHub or Email. The system browser handles identity verification, then returns you to Obsidian. If prompted to open Obsidian, confirm only when you initiated that sign-in. If a link expires, return to the plugin and start again.
Email sign-in uses a short-lived code. Check spam folders and wait before requesting another code. Never share the code with support. Google and GitHub supply basic identity and email only; they do not grant us access to your mail, Drive files or repositories.
3. Connect a cloud vault
Create a cloud vault or select an existing one, and enter its encryption password. Keep that password securely: social login cannot recover it. If creation is interrupted, follow the retry message rather than starting multiple new vaults. Let sync complete before connecting your next device.
4. Check each device
Review sync progress and any errors. Compare content and original modification times using test files. On mobile, keep Obsidian in the foreground while syncing. After reconnecting to the network, reopen the app and confirm completion. Physical-device validation is still incomplete across the six platform families.
Account deletion
Open Account → Danger zone → Delete account in the Global plugin. First delete every cloud vault and wait for cloud cleanup to complete. The plugin may ask you to sign in again to confirm that it is you; use the same account. Read the warning and type DELETE when requested.
Deletion removes your account access and connected identities. Remaining paid service time does not block deletion. Local notes remain on your devices. Signing out or uninstalling the plugin does not delete the account. Retention details.
