Your own details live under your name at the bottom of the sidebar → View profile. Name, phone and password are yours to change; your role and permissions are not, and that separation is the point — a user who could edit their own role could grant themselves anything.
Changing your password
From the profile screen. Minimum ten characters. Longer beats more complicated: a memorable four-word phrase is both easier to type and considerably harder to break than eight characters of punctuation you have to write down.
Changing it does not sign out your other sessions, so if you are changing it because you suspect something is wrong, sign out everywhere as well.
If you are locked out
Only the account owner can reset another user's password. Not admins generally — specifically the owner, the person whose signup created the account.
This is deliberate and worth understanding rather than working around. Password reset is the most direct route to impersonating someone: whoever can reset your password can log in as you and act with your permissions. Restricting it to one identifiable person makes that a decision somebody owns rather than a capability spread across everyone with an admin badge.
If the owner is unavailable, there is a self-service forgot-password flow that emails a one-time code — but it is available to the account owner only, for the same reason.
The practical consequence: do not let the owner account belong to someone who has left. An owner account tied to a departed employee's email address is a genuine operational risk — the one route back into a locked account leads to a mailbox nobody can open. If that describes your setup, fix it before you need it.
Your email address
Your email is your login. It has to be unique within the account, and changing it changes what you sign in with — worth being sure about before you save.
What you can and cannot see
Your role decides that, and it is set by an admin. If you cannot reach a screen you expect to, the answer is your role's permissions rather than anything on your profile. See custom roles and permissions.
One thing worth knowing regardless of role: leads are not hidden from you based on who they are assigned to. Assignment marks ownership, not visibility. If you expected otherwise, that is explained in why every team member can see all the leads.
Signing out
Top right of any screen. Worth doing on a shared or public computer — sessions persist, and the next person to open the browser inherits yours.
