THE SHORT ANSWER

Ask for access in Slack. Deliver the credential somewhere else: an account invitation if the service supports one, or a one-time link. If a password already went out in a channel, rotate it. Deleting the message is not the fix.

Someone needs a login. You type it into Slack, hit send, move on.

Slack is a good place to ask for access. It’s a poor place to leave the password itself. You can keep the convenience and lose most of the exposure.

01

What actually happens to a password in Slack

A credential posted in a conversation stays there under the workspace’s retention settings, visible to whoever can see that conversation. On some plans, workspace owners can export message history, including direct messages, through Slack’s export tools.

It is not true that every Slack message is kept forever, or that every admin can read every DM. Retention is configurable. Export access depends on the plan and on who is authorized. The honest, useful version is narrower: a password in a chat can remain accessible longer, and to more people, than you intended when you pasted it.

The same logic applies to Teams, Discord, Google Chat, and email. If the tool keeps history, it keeps your credential with it.

02

Keep the request in Slack. Move the secret out.

Ask what access is needed. If the service supports it, send an individual invitation with the right role. That’s easier to revoke later than a shared password, and it usually grants less than a full login.

If a credential really has to move, paste it into a one-time link and send the link in Slack instead of the password. The recipient opens it, sees the credential, and the hosted copy is deleted.

Don’t paste the secret back into the thread to confirm it. Ask whether access worked.

03

What a one-time link changes, and what it doesn’t

After the note is opened and deleted, your Slack history holds a dead link instead of a live password. That removes one place the credential could linger. Gliiph does this with encryption in your browser, so we never see what you shared either.

It doesn’t make the situation risk-free. The link is sensitive until it’s opened. Someone who gets to it first can open it. The recipient can copy or screenshot what they see. And a one-time note delivers a credential; it doesn’t revoke one.

04

If a password was already shared

Follow your organization’s process. If exposure is possible, changing or revoking the credential matters more than deleting the message. Deleting a message does not invalidate a password.

Then set the approved method before the next urgent request, so nobody has to improvise. The client access checklist is a good place to start.

ONE LESS THING IN THE THREAD.

Keep the conversation.
Skip the lingering secret.
