Description
Login Links allows you to create temporary, password-less access links for existing users or guest accounts. The links can be configured to expire either after a certain period of time or after a set number of successful logins.
How Login Link Works
A login link is a special link that, when clicked, automatically logs the user in. They don’t need an account. The login occurs either under an existing account or under a temporary account created specifically for this link. The link has an expiration date, after which it is automatically deleted.
Provide Temporary Access
Create a login link with a specific role for support teams, clients, developers, or guest users who need temporary access to the site, and email it directly to them. They don’t need to create an account or come up with a password, and you won’t have to worry about deleting their account later.
Passwordless Access for Users
Allow already registered users to log in without a password. Users request a one-time login link by entering the email they used during registration, and the link is sent to that email.

FAQ
-
What is a login link?
-
A temporary login link allows users to log in without a password, and you can set the link to expire after a specific period of time or after a certain number of successful logins.
-
How secure is this?
-
The links have alphanumeric tokens longer than 60 characters. Such a token is impossible to guess. The tokens are stored in database encrypted, this means that even if someone get access to the database, they won’t be able to use the encrypted token.
-
Can I create multiple login links for the same user?
-
Yes, you can generate multiple temporary login links for the same user, each with its own expiration time or login limit.
-
How do I prevent the link from being used after it expires?
-
The plugin automatically invalidates the link after it reaches its expiration time or the maximum number of allowed logins is reached.
-
Can temporary login links be created for guest or temporary users?
-
Yes! You can generate login links for temporary users without needing to create permanent accounts.
-
Can users still log in with a password?
-
Yes. You can choose to either disable password login or allow the user to decide.
-
What problems does this solve?
-
Users often set simple passwords, especially temporary users like developers who are given admin access. Using login links solves this problem, and you don’t have to worry about deleting the account later.
-
What about already registered users—why should they log in without a password?
-
It’s more convenient. People often forget their passwords or set simple ones to avoid forgetting them. With login links, forgetting a password is impossible because no password is required. The login is done via a one-time link.
