Unfortunately there are some phishing emails going around at the moment, and you might receive some that look like they have come from school staff. They usually have “Important” followed by a reasonable looking title and if you open them there is a button inviting you to click. Please do not do this.
If you do click you will be taken to a web page which will ask you to fill in your email address and password. Please do not do this.
If you do fill these details in then the “person” or computer that receives the information can login to your account and use your email to send further phishing emails to other people. They also sell lists of email addresses and passwords to others.
If you suspect you have accidentally given your details, or your friends are getting these phishing emails from you, change your password.
