Email One-Time Password Authentication
Validates credentials and password if exists in current session or generates ones for session time on empty password which is treated as one-time password request and sends it to an email. Matches only valid email from allowed domains using global
denyemailaddresses settings if set.
Additional security can be set:
- revoke threshold: login failures limit causing revoke of the generated password, works independently of the account lockout (
lockoutwindowsite security settings) and covers additionally signing up
- minimum request period: a time in seconds after which another password can be generated
Signup and user creation on first login if not prevented (global setting
authpreventaccountcreation) takes place only in case of using email as username (not to be confused with the
authloginviaemail global setting) and parts
of email address may be mapped to profile fields using PCRE expressions.
Auth instruction setting (global
auth_instructions) is recommended depending on the adopted user account policy and plugin configuration.
