Cache, data and credentials are three different things
Clearing cache only removes temporary files and is safe routine maintenance; clearing data also wipes your login state. Choosing the wrong one signs you out, which is awkward if your second factor is not to hand.
What to prepare before you start
These five things cover almost every delay people run into: Confirm your second factor works, since you may need it if signed out.
Make sure you remember your login password. Understand that clearing cache never deletes balances or order history.
Plan to reopen the app afterwards and check things work.
Five steps for a safe clean-up
Follow the order and your login stays intact: Prefer the in-app clean-up option if present, which removes temporary files without affecting login.
In system settings choose clear cache, not clear data. Reopen the app afterwards and confirm you are still signed in.
If you were signed out, log in again from the official entrance and complete the second factor. After clearing, verify that price alerts and notification settings still work.
Fees, limits and processing times
Numbers change from time to time, always confirm on the official fee page before you commit size: The help centre and in-app support cover most issues; for fund-related cases open a ticket and keep the reference number.
Nobody from real support will ask for your password, 2FA code or seed phrase - treat anyone who does as a scammer. Spot, margin, perpetual and dated futures, plus options, sit at the core of the platform.
Strategy tools such as grid and DCA bots, copy trading, OKX Wallet with its DEX aggregator, and Earn products extend well beyond simple trading. Set a separate fund password alongside Google Authenticator, then enable the anti-phishing code and address whitelisting.
Review login devices regularly and expect extra checks after changing SIM, email or device.
The OKX-specific part
OKX app cache grows with use too, and the clean-up entry sits in settings. If clearing does not help, try updating to the latest build or reinstalling the client.
Frequently asked questions
Does clearing cache delete my assets
No. Balances and orders live server-side, so local clean-up does not affect them.
Do I need to re-verify after being signed out
Usually you only sign in again and pass the second factor, not redo identity verification.
How often should I clear it
Whenever it feels sluggish or storage runs low; there is no fixed schedule.

Do not use unfamiliar "cleaner and booster" tools. After clearing, check that notifications still arrive.
