Parameters:

- secret - (Required) The base32-encoded secret key used to generate TOTP codes.
- period - Optional. Sets the validity period of each OTP in seconds. Must be a positive number not exceeding 120. Default is 30.
- digits - Optional. Specifies the number of digits in each OTP. Must be between 4 and 10. Default is 6.
- algorithm - Optional. Defines the hash algorithm for generating OTPs. Supported values are SHA1, SHA256, and SHA512. Default is SHA1.

Generating a TOTP Secret

To generate a TOTP-compatible secret for use with ClickHouse, run the following command in the terminal:

```bash
$ base32 -w32 < /dev/urandom | head -1

$ qrencode -t ansiutf8 'otpauth://totp/ClickHouse?issuer=ClickHouse&secret=JBSWY3DPEHPK3PXP'
