Phone Security Guide
Protect accounts, data, recovery methods and ownership safeguards.
Strong phone security combines a unique passcode, current software, account recovery methods and careful handling of messages and links.
Start with the safest checks
Use observation and reversible tests before changing settings. Write down the exact message, recent changes and conditions that reproduce the problem.
- Use a strong device passcode
- Enable account multi-factor authentication
- Review recovery phone and email
- Install updates from official sources
- Never share one-time codes
Protect your data and accounts
Back up important information before repair, reset, sale or transfer. Never disclose passwords, one-time codes or full device identifiers in public.
- Verify backup completion
- Use official account-recovery channels
- Keep sensitive identifiers out of screenshots and URLs
Know when to stop
Stop when a phone is swollen, smoking, leaking, physically damaged or extremely hot. Manufacturer, carrier or qualified repair support is appropriate when safe checks do not isolate the fault.
- Do not puncture or open a battery
- Do not use heat, freezing or conductive tools
- Ask about warranty, data handling and cost before repair
