Fix COME login problems in the right order.
Separate a credential problem from a network or Android component problem before you reset anything.
Follow the sequence.
Change one condition at a time so you know what fixed the problem.
- 01
Read the exact message
‘Wrong password’, ‘code expired’ and a blank screen need different responses.
- 02
Check time and network
Automatic date and time help verification codes and secure connections work correctly.
- 03
Use the in-app recovery path
Request one code, wait for it and avoid sharing it with anyone.
- 04
Escalate with safe details
Share device and error information, not your password, OTP, PIN or recovery code.
Blank screen before login
Update Chrome and Android System WebView, restart the phone and test a stable network. A blank embedded page often points to the web-rendering path rather than a wrong password.
Keep the source, action and evidence in the same chain.
Verification code does not arrive
Confirm the contact method shown on screen, check spam or blocked-message filters, wait before requesting another code and avoid rapid repeated attempts. Use only the recovery route displayed by the app.
Prepare a support requestRead the device message before changing a setting.
Common questions.
Short answers first. The linked guides carry the full context.
Should I share my OTP with support?
No. Never share an OTP, PIN, password or recovery code.
Will reinstalling fix every login issue?
No. Reinstalling does not correct wrong credentials, a service outage or a verification block and can remove local settings.
Can the wrong device time affect login?
Yes. Secure sessions and one-time codes can fail when the device clock is far from the correct time.
