# Keys and Security
|
|
|
|
The following information is not exhaustive but meant to prevent the most common mistakes. You can read more about
|
|
security and risks in the [Polkadot Wiki](https://wiki.polkadot.network/docs/learn-account-generation). The Polkadot
|
|
network has a few **test networks**, e.g. **Westend**. Test networks are a great way to experiment and learn safely as
|
|
you can lose tokens on those networks without any financial consequences.
|
|
|
|
`subkey` generates and provides 2 pieces of **secret** information:
|
|
- **secret phrase**: a bunch of words, exactly 12 by default (can be 12, 15, 18, 21 or 24)
|
|
- **secret seed**: a big hexadecimal value
|
|
|
|
There are 2 risks related to private keys:
|
|
- loss of keys: this can happen if you don't have a proper backup
|
|
- leak of the keys: this can unfortunately happen in many ways, including malware, phishing, key logger, backups on
|
|
system that are online and not properly secured
|
|
|
|
You want to ensure that:
|
|
- you **do not lose** those secrets
|
|
- **no one but you can access** those secrets
|
|
|
|
☠️ **DO NOT SHARE** your mnemonic phrase or secret seed with ANYONE under **ANY** circumstances. Doing so would give
|
|
them access to your funds and to send transactions on your behalf.
|
|
|
|
☠️ If someone is asking for your **secret** phrase or **secret** seed, you can be **SURE** they are attempting to steal
|
|
your funds.
|
|
|
|
✅ It is however fine to share your **SS58 Address** as this is meant to be public information and is needed by anyone
|
|
you want to be able to make transfer to or otherwise interact with your account. They will only ever need your **Public
|
|
Address**.
|
|
|
|
⚠️ While using the same key on multiple networks is possible, it is usually **not** recommended unless you have good
|
|
motivations for doing so and understand the associated risks and drawbacks.
