Describe the Scenario

Hi Bookstack community.

I have a bookstack application that contains some sensitive data. A number of my users have checked the "remember me" checkbox to keep themselves logged in for longer. I noticed that one of my users had been logged in for over a month and I wanted to find out what the best option would be to limit the user so that the most amount of time they can be logged in is 8 hours. This is in an attempt to ensure that if the users device becomes compromised by a bad actor, that they don't have access to the bookstack data for very long.

I'm happy to remove the checkbox from the blade file so that my users can't tick it, but I wanted to see if there were any better / suggested ways of handling this instead. I'm guessing I could also setup a script to run every 8 hours that clears the files (excluding the .gitignore file) in the sessions folder as well.

Hi @RyanH264,

I'm guessing I could also setup a script to run every 8 hours that clears the files (excluding the .gitignore file) in the sessions folder as well.

No, I don't think that would do it, The "remember me" option works around sessions by storing a token in the database (table: users -> column: remember_token) which is then matched against user cookie that's placed on login with "remember me" checked.
You could automate/script updates to the users column to set that to null where not already null, to wipe out remember tokens. In this case the login will expire with the session.

As a cheeky smart alternative, you could create some triggers in the database to auto-set this to null on any creation/update:

CREATE TRIGGER clear_remember_token_ins BEFORE INSERT ON users FOR EACH ROW SET NEW.remember_token = null;
CREATE TRIGGER clear_remember_token_upd BEFORE UPDATE ON users FOR EACH ROW SET NEW.remember_token = null;

Backup the DB before playing around with things, and test the process works for your scenarios as things could differ!

so that the most amount of time they can be logged in is 8 hours.

Note that the existing SESSION_LIFETIME option does not cap the login time like that, it's how long they expire after no activity. If the user performs activity (page load, form submit etc...), the time window restarts for another SESSION_LIFETIME amount of minutes again.

Thanks Dan!

Triggers sound like the way to go. I'll be sure to fill in my change management forms, schedule the update outside of peak times, perform my backups and update this thread once the change has been implemented into prod so that anyone else looking for this functionality can see how my implementation went.
