Temporary passwords and one-time codes
Learn the difference between a temporary password, a one-time code, and a random PIN.
A temporary password works only when the website or app sets an expiration rule. Making a random password and calling it temporary does not make it expire or stop working after one use.
The account decides when access ends
A website or app can require someone to change a temporary password after the first sign-in. It can also reject a code after a few minutes or after one use. The account has to enforce those rules. A password made by this generator will keep working until the account owner or service changes it.
Authenticator apps create codes from a secret shared with the account. A time-based code, often called TOTP, usually changes every 30 seconds. A counter-based code, called HOTP, changes when it is used. A random six-digit PIN from this site is not connected to an account, so it cannot replace either kind.
Use the account’s invitation, password-reset, or temporary-access feature when one is available. Avoid sending the username and password together in a group chat, public message, or unencrypted email. Make sure the person receiving access can replace the temporary password after signing in.
