Session Sharing vs. Password Sharing: What's the Difference and Why It Matters
When someone says "sharing access," most people think of one thing: giving someone the username and password. That is password sharing. It has been the default for decades and it is fundamentally insecure.
Session sharing is a different concept entirely. Instead of transmitting the credential, you transmit the session. This is a temporary, authenticated state that lets someone use an app without ever seeing the login details.
Here is why the distinction matters.
What is password sharing?
Password sharing means giving another person your actual login credentials, including your email and password, or a link with credentials embedded. Once they have it, they can:
Log in from anywhere, on any device
Change the password and lock you out
Share it with others without your knowledge
Keep using it indefinitely, even after they should no longer have access
The moment you share a password, you have lost control of it. There is no undo. The only way to regain control is to change the password, which disrupts everyone else who might be using it.
What is session sharing?
Session sharing works differently. Instead of handing over credentials, you share an authenticated browser session. This is essentially a cookie token that proves the person is already logged in.
The recipient gets access to the application through that session, but:
They never see the password. It is not transmitted, displayed, or stored on their end.
The session is temporary. It can be set to expire after a certain time.
You can revoke it instantly. One click, and they are logged out with no password change needed.
There is a record. You can see when the session was used and by whom.
Why this distinction matters for security
The core security principle is simple: if someone does not know your password, they cannot misuse it.
With password sharing:
Credentials exist in chat histories, notepads, and memory
Each person who knows the password is a potential leak
Revoking access means changing the password for everyone
With session sharing:
Credentials stay with the owner
Access is granular and time-bound
Revoking access for one person does not affect anyone else
Real-world analogy
Password sharing is like giving someone a copy of your house key. They can come and go as they please, make more copies, and you cannot take it back without changing all your locks.
Session sharing is like letting someone in through a smart lock with a temporary code. The code expires, you can delete it anytime, and you can see exactly when they entered and left.
When to use each approach
Use password sharing (via a vault like 1Password) when someone needs permanent, ongoing access and you trust them with the credentials long-term.
Use session sharing (via SessionShare) when access should be temporary, when you do not want the password exposed, or when you need to maintain control over who is logged in.
The shift happening right now
Teams are starting to realize that sharing the password was never the goal. Sharing the access was. Session sharing gives you the access without the risk. It is a fundamental upgrade in how we think about collaborative authentication.
