+## TOTP Two-Factor Authentication
+
+TOTP Two-Factor Authentication is a feature of TDengine TSDB Enterprise Edition, support in version v3.4.0.1 and above.
+
+### Create/Update TOTP secret
+
+```sql
+CREATE TOTP_SECRET FOR USER user_name
+```
+
+If the user has not yet created a TOTP secret, this command will create a TOTP secret for the user. If the user has already created a TOTP secret, this command will update the secret for the user. In either case, this command will return the newly created secret, which will only be displayed once, please save it promptly. The system will automatically enable TOTP two-factor authentication for users who have a TOTP secret.
+
+For example, we can use the following command to create a TOTP secret for user test.
+
+```sql
+taos> create totp_secret for user test;
+                     totp_secret                      |
+=======================================================
+ ERIRPLZL4ZBFTPT5BNXMVFPR4Z3PTHUWTBTCNZPOHYPYQGTD25XA |
+Query OK, 1 row(s) in set (0.002314s)
+```
+
+### Drop TOTP Secret
+
+```sql
+DROP TOTP_SECRET FROM USER user_name
+```
+
+This command drops the TOTP secret from the user. After the secret is dropped, the user's TOTP two‑factor authentication will be disabled.
+
+For example, we can use the following command to drop the TOTP key from user test.
+
+```sql
+taos> drop totp_secret from user test;
+Drop OK, 0 row(s) affected (0.002295s)
+```

+## TOTP 双因认证
+
+TOTP 双因认证是 TDengine TSDB 企业版功能，从企业版 v3.4.0.1 开始支持。
+
+### 创建/更新 TOTP 密钥
+
+```sql
+CREATE TOTP_SECRET FOR USER user_name
+```
+
+如果用户还未创建 TOTP 密钥，此命令将为该用户创建 TOTP 密钥。如果用户已经创建了 TOTP 密钥，此命令为用户更新该密钥。不论哪种情况，此命令会返回新创建的密钥，此密钥仅展示一次，请及时保存。系统会为创建了 TOTP 密钥的用户自动启用 TOTP 双因认证。
+
+例如，可以使用下面的命令为用户 test 创建 TOTP 密钥。
+
+```sql
+taos> create totp_secret for user test;
+                     totp_secret                      |

+ ERIRPLZL4ZBFTPT5BNXMVFPR4Z3PTHUWTBTCNZPOHYPYQGTD25XA |
+Query OK, 1 row(s) in set (0.002314s)
+```
+
+### 删除 TOTP 密钥
+
+```sql
+DROP TOTP_SECRET FROM USER user_name
+```
+
+此命令删除用户的 TOTP 密钥，密钥删除后，用户的 TOTP 双因认证功能将被禁用。
+
+例如，可以使用下面的命令删除用户 test 的 TOTP 密钥。
+
+```sql
+taos> drop totp_secret from user test;
+Drop OK, 0 row(s) affected (0.002295s)
