Account & sign-in
What if I forget my password?
The login page has a "Forgot password" option: if your account has an email bound to it, you can reset the password with a verification code sent by email; if you can't recover it yourself, contact an administrator to reset it. See Registration & Login for details.
Why do I have to sign in again on every client after changing my password?
This is a normal security measure: changing your password invalidates the login state on all signed-in devices, including devices using passwordless sign-in.
Getting an "unauthorized" message, or being signed out right after signing in?
Check whether the device's system time is accurate — credential validity is judged from timestamps, and a large clock deviation can make verification fail.
The QR code for sign-in can't be scanned / has expired?
The QR code is time-limited (about 2 minutes). After it expires, click refresh on the computer to generate a new one, then use "Scan" in the phone app.
Switched to a new phone / reinstalled the app — is my data still there?
Yes. Entry data is stored on the server; sign in with the same account and all your data is restored. Before switching devices, it's a good idea to unbind the old one in its Security Center to keep your device list clean.
Data & statistics
Why doesn't a certain entry show up in statistics?
Check whether that entry has "Exclude from income & expenses" turned on — such entries only show up in the transaction list and are left out of income / expense statistics (for transfers, internal moves, and the like).
The budget's "used" amount doesn't match actual spending?
Budget statistics leave out entries with "Exclude from budget" turned on, and entries whose category has "Exclude from budget" enabled. This is by design, so the budget reflects real spending pressure.
Deleted an entry by mistake — can I get it back?
Deletion cannot be undone, so be careful. Important data can be backed up regularly with "Data export" (see Updates & Data Security).
Can historical data be imported?
Yes. Contact an administrator to help with a one-time import of your historical data; once imported, those entries are included in statistics and analysis just like any other data.
Feature availability
The AI assistant says it's unavailable?
The AI assistant depends on the AI service configured on the server. While it isn't enabled, AI chat and the AI profile are unavailable; other features are not affected.
Can I connect the AI client I already use?
Yes. Create an "MCP Only" API key in the Web app's Security Center, then enter the server URL and key in your AI client — see Connect AI Clients (MCP) for the full steps. The key is equivalent to your account access, so never post it publicly.
Why is an analysis feature missing on my phone?
Analysis capabilities are being brought from the web app to the other clients step by step; for now, the web app offers the complete experience. See the feature matrix for what each client covers.
Access & network
The web app won't open?
- Make sure you are using the official address bk.minbb.cn
- Try refreshing the page or switching browsers (the latest Chrome, Edge, or Safari is recommended)
- If it's still unreachable, use Feedback or contact an administrator to check the service status
The app reports a network error?
Check the device's network connection; once the network is back, pull down to refresh and the data syncs. Data already loaded while offline stays viewable.
