App to exchange with self-destroying links

Hi! I am looking for an application, which may be used by users to exchange with some sensitive information in the form of generated links, which will be destroyed through certain time.

Eg, if I need to send a password to my colleagues and I do not want to type it in a plain text, I may use this service, which will create quick link, which will lead to the word with password, and will be destroyed either once after its using or in a pre-defined time interval.

UPD: somehow this app may replicate the Passman app, though much easier.
