Is this normal security check or have I been scammed? I did change my password and security question just in case. Any help would be appreciated, many thanks.&nbsp;</P> Mon, 16 Jun 2025 17:46:48 GMT J20513 2025-06-16T17:46:48Z https://community.o2.co.uk/t5/Other-Products-and-Services/Does-O2-ask-for-one-time-passcode-via-online-chat-on-O2-app/m-p/1798200#M55380 <P>I was chatting to what I thought was someone working at O2 via app chat, wanted to cancel my Apple Watch tariff, until he or she asked for one time passcode?
