{% hint style="warning" %}
Do not use the restricted names, such as but not limited to:

help, bitmask, diba, [diba.io](http://diba.io/), team, support, admin, info, contact, feedback, security, privacy, carbonado, bitmaskadmin, help.bitmask, bitmask-help, bitmasksupport, team-diba, team-bitmask, dibateam, and bitmaskteam.
{% endhint %}

### How can I use a different network (i.e. switching to testnet)?

BitMask supports Bitcoin L1, Testnet, Signet, and Regtest. To switch between networks, click on the Bitcoin button located in the top right corner, as all BitMask wallets operate on Bitcoin L1 as the default setting.
