Don’t leave logins on your clients’ sites.
Storing login credentials for your customers is a security risk: if you get hacked, logins to all your clients’ sites are compromised. Instead, delete all those logins from your password manager and let your customers grant access with a single click.
Faster and more secure.
Add TrustedLogin as a plugin on your clients’ sites. Then each time clients request changes, they can click a link to grant you access using TrustedLogin. It’s as simple as that.
