Overview
WordPress sites can face risks from weak login credentials, repeated login attempts, and vulnerable plugins or themes. iThemes Solid Security Pro addresses these areas with login requirements, two-factor authentication, passkeys, and brute force protection. Site owners can set password and authentication requirements for users, while local and network-based IP bans help block malicious login attempts.
The plugin also includes vulnerability scanning and management, a security dashboard with customizable alerts, and notifications about logins from unrecognized devices. Trusted Devices can help control access from familiar devices. For site administration, user activity logging records actions, WP-CLI support provides command-line management, and temporary privilege escalation lets administrators grant outside developers or technicians limited access for a set duration.
Features
- Login security requirements: Set requirements for strong passwords, two-factor authentication, and passkeys to help protect user accounts from weak credentials and unauthorized access.
- Brute force protection: Use local and network-based IP banning to block malicious login attempts, with settings that can be adjusted to your needs.
- Passkeys and two-factor authentication: Strengthen sign-ins with passkeys and two-factor authentication, including biometric login compatibility across supported browsers and devices.
- Vulnerability scanning: Schedule scans to find vulnerable software and manage virtual patches when updates for the affected software are not yet available.
- Trusted device controls: Approve familiar devices for secure sign-ins and receive notifications when users log in from unrecognized devices.
- Temporary admin access: Grant developers or support technicians temporary administrative access without creating new accounts, and set the access duration and permissions.
- Activity logs and WP-CLI: Review detailed records of user actions and manage security tasks through command-line tools designed for developers.
