# 設定安全總覽

![設定安全總覽](/files/Vl7SPKIezgoQgGqW8Vk5)

前三篇教你「停・查・問」、教你一眼識破假訊息、也帶你認過 12 種常見手法，靠的都是「臨場反應」。這一篇換個做法：與其每次都靠當下的警覺，不如花十分鐘，把手機與帳號的幾個開關「事先設定好」，從源頭就少掉一大半被詐騙接觸、被盜帳號的機會。

詐騙要得手，常得先跨過幾道門：**先能聯絡到你**、**能登入你的帳號**、**能盜刷你的卡**，甚至**能動你的房子**。這一篇就針對這些破口，給你幾個最划算、設定一次就長期有效的基本防護。

| 章節                                                            | 一句話重點                                  |
| ------------------------------------------------------------- | -------------------------------------- |
| [關閉陌生人加 LINE 好友](/fraudhuntertw/settings/line-privacy.md)     | 關掉幾個開關，詐騙就很難用外洩的電話或 LINE ID 加到你、傳訊息騷擾你 |
| [密碼安全](/fraudhuntertw/settings/password.md)                   | 一站一密碼、開雙重驗證、用密碼管理器，帳號被盜的機率大幅下降         |
| [信用卡防盜刷](/fraudhuntertw/settings/card-overseas.md)            | 平時關掉用不到的海外刷卡、開即時消費通知，卡號外洩也難被盜刷         |
| [不動產防詐：地籍＋稅籍異動即時通](/fraudhuntertw/settings/property-alert.md) | 有人對你的房子辦登記或報稅就即時通知你，第一時間喊停             |

> 這一篇的設定多半「只要做一次」，卻能長期保護你。建議現在就找個十分鐘，拿起手機跟著做一遍；順手幫家裡長輩也設一次，效果更好。
