Sentinel Federal Credit Union warns all members to be extremely cautious when they are asked for personal or financial information over the phone, by email, through a text message or the Internet. They are advised not to give out personal information unless they have initiated the contact and are sure they know who they are dealing with. Identity thieves are clever, and may pose as a representative of your Credit Union to get you to reveal your sensitive information. The thieves or scammers may use pressure to get you to act immediately or use scare tactics or harassment to trick you into sharing your personal information.
