Following basic security measures can help you stay away from scams. Kindly follow them by heart:
Never use the Same Password for email and Splinterlands. It is recommended to use different passwords & use a end to end encrypted Password Manager to generate new passwords
Please Keep Active Authority Turned On. This can be accessed in settings.
Use Hive Keychain for transactions & never copy paste Active/Owner/Keys or Master Password. For mobile users, please download hive keychain app and use internal browser to interact with markets to avoid keys copy/pasting.
Never click on any links/offers you receive in DM or someone claiming to be a tech support. Tech support will never DM you directly unless asked. Also you are not allowed to share you passwords, keys or personal secret information with tech support. So never share anything personal, especially on public channels.
Save Your Keys offline, Nobody can take care of them better than you. Remember this: Not Your Keys, Not Your Crypto
