Keep your linked devices safe

Every device you link — desktop app or KT Web — gets its own encrypted session. Your phone stays the anchor of the account.

Review them

Settings → Linked devices lists each one with the platform and when it was last active. Anything you don't recognise, sign out immediately.

Good habits

• Sign out of shared or public computers when you're done.
• Turn on app lock on devices other people can reach.
• Never scan a login QR code someone else sends you — that hands them your account.

Lost device

Sign it out from any other linked device. If you've lost the phone itself, re-verify your number on a new one — that ends the old sessions.
