About this tool

Type a password to see its length, the types of characters, an entropy estimate in bits and a rough time to guess it. The check runs in your browser and the password is never sent or saved.

How to read it

Longer is stronger. Entropy in bits grows with length and with a wider mix of characters. Above about 60 bits is good for most accounts, and above 80 is strong. Common words and patterns are weaker than the estimate suggests.

Tips

Use a long passphrase of several unrelated words or a random password from a manager. Use a different password for every account and switch on two-step login.

獲得最佳結果的提示

在相信結果之前先檢查每一個輸入項，因為一個錯誤的數字就會改變整個答案。請使用工資單、賬單、證書或合同上的準確數字，並記下計算日期。稅率、門檻和規則會不時變化，因此對於稅費和法律事務，請將結果視為估算，並與本頁註明的官方來源核對。您可以嘗試任意多個方案；不會儲存或傳送任何內容，重新整理頁面會清空輸入。
