Your first lock
Create your first session
To create your first Chaster session, you will need:
- A chastity device, that can be locked with a key.
- A key lockbox (a small box with a resettable numeric code), where to put the key in a safe place during the session. A supported smart lockbox also works.
You can also test the application without actually locking your lock box, to test the features before a first real chastity session.
On the Locks page, click on the Create a lock button. You can now configure the parameters of your lock.
Initial duration
Chaster locks are time-based locks, the session starts with an end date randomly determined between the minimum and maximum durations. You can set manually these two durations.
The initial duration will be set randomly between these two durations.
Lock options
You can enable or disable certain options that will change the behavior of your lock. View all lock options
If you are a beginner, we advise you to enable the Limit lock time option, to limit the maximum time spent locked.
Safety & control
Review Emergency unlock and your permissions before starting. Emergency unlock lets you end an enabled session immediately and retrieve your combination. Its initial choice follows Settings > Lock defaults. You can also choose a confirmation phrase, or leave it blank for the default. See Emergency unlock for configuration and release steps.
When joining a shared lock instead, review its emergency-unlock choice and permissions on the Review your lock step. The creator can impose on or off, or let you choose. Your account default only applies when the choice is yours.
Features
You can enable some community features that will allow you to share your lock with others, and allow them to do actions. With Shared Links, you can for example send links to other people to ask them to add or remove time. View all features
"Offer your session" is enabled by default. This lets you offer your lock to a keyholder during or after creation.
If you uncheck "Offer your session" when creating your lock, you are explicitly choosing to disable it, and this cannot be changed for the lifetime of the lock. The lock will remain a self-lock forever; you cannot re-enable the option later, and moderators cannot enable it for you. Many users ask support to enable this on an existing lock, but it is not possible. Only uncheck it if you are certain you will never want a keyholder for this lock.
Extensions
Extensions are the core of Chaster, and allow infinite customization. There are all types of extensions: games, tasks, punishments, etc... You can activate them or not according to your desires and the experience you want. View all extensions
New extensions are developed every month, and are available in preview if you are a Plus member.
Locking method
Chaster keeps you locked by holding the way back to your key until your session ends. You choose how on the Locking method step:
- Combination picture (recommended): you photograph the dials of a key lockbox and never see the code.
- Generated code: Chaster gives you a code to set on a key lockbox. You see it briefly.
- Smart lockbox or device: a connected device that stays closed until your Chaster lock ends. There is no code at all.
The first two work with any key lockbox: a small container with a resettable numeric combination. You place your chastity key inside, set a code you don't know, and let Chaster store it for you.
Combination picture
This is the recommended method because you never see the combination at any point.
- Open your lockbox and place your chastity key inside.
- Set a new combination without looking: turn the dials randomly with your eyes closed or while looking away.
- Take a picture of the new code without looking at it: hold your phone over the dials and snap a photo while looking away.
- Upload the photo to Chaster when creating your session.
- Scramble the dials and close the lockbox: you are now locked out.
- Start your session and delete the photo from your phone.
Before uploading, you can glance at the photo just to check it's not blurred, but avoid reading the numbers. If you are worried about image quality, you can request a verification of your photo: a moderator will confirm the image is readable once the session has started.
Generated code
With this method, Chaster generates a random numeric code for you.
- Choose the number of digits matching your lockbox.
- Chaster displays a code: set this code on your lockbox.
- Lock the lockbox, scramble the dials, and start the session.
The combination will be revealed again at the end of your session.
This method requires you to read the code in order to set it on your lockbox. Your session security depends on you forgetting the combination. For stronger enforcement, use the Combination picture method instead. If you prefer this method, consider using it for shorter sessions where the code is easier to forget.
Smart lockbox or device
A smart lockbox is a connected key safe that works with Chaster. You put your key inside, close it, and the box only opens when your Chaster lock says so. Adding time, a hygiene opening and unlocking all reach the box, so your keyholder can control it from anywhere.
On the Locking method step, pick one of our partners' devices, or search every supported device. Then follow the device's own configuration screen, for example to pair the box.
Research and Desire Lockbox
A smart key safe built for chastity keys. It connects to Wi-Fi on its own and stays powered over USB-C, so your keyholder's actions reach it within seconds, even when your phone is off or out of reach.

- Read the Lockbox guide: setup, pairing, breaks and safety.
Reach Lock
A timer lockbox from Reach Restraints, in an ultra-durable case paired to your phone over Bluetooth. It comes in M (most chastity keys) or L (keys up to 8 cm), with a normal or see-through lid. The Standard version has a discreet pinhole release as a last resort if Bluetooth fails or the electronics are damaged; using it counts as an emergency unlock. The High-Security version has no pinhole.
A lock has exactly one locking method. To switch between a combination and a smart lockbox on a running lock, start a hygiene opening and choose the new method when you lock again.
